- R: Rotate
- Esc: Menu

How to Play:
- Fill an entire line and stand still to clear it.
- Keep moving downward!

Change Log:
- 2025.4.9: Fixed a bug where rotating the player could overlap with moving blocks by disabling rotation in such cases.
- 2025.4.13: Fix the bug where rotating the player could overlap with blocks in a more clever way (and undo the 2025.4.9 fix!)

This was a really clever twist on tetris, utilizing game mechanics we're all familiar with and applying them to a whole different genre. Nice job!

had a blast beating this one! great idea and well executed.

Great concept, very unique mechanic!

Short and sweet! the platforming was a little weird at times, especially the first time I needed to push the green block but overall very fun!
SYPIAC7 Apr 2025, 06:28
I seem to have bugged out the physics and launched the needed block across the whole map into a corner right before winning the game, so I can't say I beat it. Great otherwise! Very innovative.

Took me a while to realize you have to stand still to complete the column, I like running around all the time so it was a minute before I got off the title screen :laughing:

@sypiac Thanks for playing! If you run into a bug, you can restart the level from the ESC menu. Honestly, there are quite a few physics bugs in my game 😂

Update 2025.4.10: I think now the bug is fixed!😊

Very fun design! I like this stick tetris and the way you made levels, very interesting concept.The levels themselves could be more polished though, like adapt a lager scaled grid, make key infomations nice and clean and etc... but its just compo, concept alone is more than enough to be liked!

Probably one of the best entries I've played so far. Great idea and very well executed. It's both chill and clever: I love it! :heart:

Hey, I won!
Nice! Never seen this mechanic before (except tetris, ha-ha), very innovative! Maybe do some polish and this will be great complete game!

Really fun game and a well executed new take on the tetris formula! I think you will get really good ratings on this one!

This is so smart!!! 10/10 innovation tbh. Never considered tetris as a platformer haha!!! Definitely fits the theme too!!!

Cool unique idea. Detection for the pieces to fill lines seemed a bit hit and miss though.

Really creative take on a classic game. Fits the theme really well and plays pretty smoothly. Might be on my end but the blocks take a while to get rid of the row but other than that the game plays really nicely!

Rinevardauthor8 Apr 2025, 00:45
@clare-chan1738 Thanks for playing! The decay of block clearing is intended, the player have to stand still to make the line cleared. This gives the player more control over their fall. Sorry for not explaning it in the game.

This was pretty cute! It was like tetris the puzzle-adventure game. I liked how there were always paths to jump back up to higher levels if you forgot to bring something with you.

Got stuck a few times at the first green piece. Interesting concept!
LDJam user 3576568 Apr 2025, 02:50
That was really cool! A very creative take on the tetris theme. There is some buggy behavior when rotate without enough room. The way you designed the levels to introduce mechanics without being too punishing was stellar, too! Great job!

What an awesome take on Tetris! This was a really great game. I could play this for a very long time. I think I found a bug. I was rotating on top of the l shape and then suddenly it clipped through the level. Other than that, this was great. Well done!
yangtuofeel8 Apr 2025, 04:04
This game is amazing! It's hard to imagine that it was done by one person. I'm a big fan of puzzle solving, and this game is really, really good.

Rinevardauthor8 Apr 2025, 04:10
@pres2300 Thanks for playing! I’ve noticed some bugs with the green L piece too. I’m not sure how to fix them yet, but I’ll definitely look into it when I get some time. Appreciate your feedback!

Update 2025.4.10: I think now the bug is fixed!😊

This is really sweet small tetris puzzler. I love how you combined both "genres" and also the soundtrack and the effects are really cute! Cool game! :D
MEGA Marlon8 Apr 2025, 08:59
It always surprises me when people can push Tetris into new territory. This was awesome! I had a little trouble lining up the block you have to push, but other than that really interesting and fun take on Tetris!

Lovely game ! Me and my kids would love to play a full version of this. It has very good puzzle elements with multiple solutions, which is very forgiving. I love that ! Audio and art also were working very well together. Thank you and congratulations on such a nice entry !

Really cool game! You bring something new to the Tetris world, I really like you puzzle design using this classical mechanics.

Hoping to play you game on steam one day.

Wow this was so cool! I've never seen a tetris twist used like this, and it is very well executed. This one frustrating point in that you or your pieces are often getting stuck, but the rotate commands recover pretty much everything.
This congratulation screen is brilliant! Really cool use of the mechanic

Got stuck in one of the levels through some weird bug. Not sure how it happened. Could not extract myself. Still, very creative. An unusual game.

@gamebuilder Sorry to hear that, you can restart the level in the Esc menu if you want. Appreciate your feedback!

As others have already mentioned, really clever take on an existing game that plays well with the original rules! Especially mechanics like rotation opened up a lot of doors for more interesting puzzle designs and level layouts. I experienced 2 small softlocks with pushable objects getting stuck in places or the player getting stuck (but as already mentioned restarting the level worked fine for my purposes). Overall fun to play. Great job!

sadvest9 Apr 2025, 10:51
Very creative design! The reward at the end of the level feels really satisfying. One issue I encountered is that when there isn't enough space after rotating, I get stuck and end up being strangely stretched. Also, I noticed the player and movable blocks are slightly smaller than the environment blocks. Curious about the reason behind the design. Nice work!
Rinevard
Rinevardauthor9 Apr 2025, 11:12
@sadvest Thanks for playing and you really have keen eyes! The player and movable blocks are slightly smaller because I've found they can't fit in the interval if they have the same collision size with the environment blocks. In fact, many of movable blocks have circle or ellipse collision to make them correctly fit in the intervals. As for the rotation stuck, I had decided to only allow rotate if there is enough space, but end up having no time implementing this.The stretch is because the player is streched if they are not on floor, which makes jumping feel better. 😊

Loved it. Excellent concept.

Physics is hard... :stuck_out_tongue_closed_eyes:

This helped me with a similar problem (property on RigidBody2D):

I think ideally you would use "Cast Shape" but that doesn't seem to work for me at all...
Rinevard
Rinevardauthor9 Apr 2025, 14:24
@dstoc Thanks for playing and your feedback! Unfortunately using "Cast Ray" and "Cast Shape" both doesn't work. I disabled rotation ability when it causes overlap with moving blocks, I hope it helps.

mmm excellent twist on tetris and combining it with platforming! 10/10 innovation. I do wish the platforming section can be more challenging, taking advantage of our rectangular-shaped character, but still really really unique entry, I love it.

好厉害的创意!这次 LD 最惊喜的游戏!期待能在这个玩法基础上设计出更有趣的谜题。加油!

Amazing innovation! The most surprising game I've played in LD57. I'm looking forward to more puzzles based on this gameplay. Very good job!

Really cool! I like the colours and the puzzle gameplay elements especially. One time I got a block stuck, but the levels are short enough so restarting was fine
Mikan
Mikan13 Apr 2025, 21:26
Very cool concept. It would be even better if we could pull the block, sometimes it will be pushed to a position where it cannot be taken out.
Rinevard
Rinevardauthor14 Apr 2025, 23:03
@mikan Thanks for playing! I noticed that sometimes the block gets pushed into a position where it cannot be retrieved. 😂 If I continue working on this game in the future, I will definitely add the ability to pull blocks back.

Nice use of tetris's mechanics, it gives birth to a super creative plateformer. Weel done :)
MoD_Wiz16 Apr 2025, 12:11
It's a very interesting idea that is well done. Always a delight to see more puzzle platformers in this jam. I wish it would have more levels and maybe mechanics, but the length is good considering timeframe, especially for COMPO entries. Also i managed to softlock myself 2 times, so maybe a dedicated reset level button would be nice, I used R in my submission.
I hope this idea will be developed further!
Rinevard
Rinevardauthor16 Apr 2025, 22:53
@mod-wiz Thanks for playing! If I continue working on this game in the future, I'll try my best to avoid softlock. I think adding the ability to pull blocks could help a lot.

Good puzzles, but i have a problem in a start - it's not very intuitive, that u need to press "up" or "down" for " puzzle stripe's of blocks" disappearing.
Rinevard
Rinevardauthor17 Apr 2025, 13:20
@oeuegha Thanks for playing! Pressing "up" or "down" is not necessary, the player have to stand still to make the line cleared. I used to think that this gives the player more control over their fall. Sorry for not explaning it in the game.
