CrystalsTD
CrystalsTD is a tower defense game set in a futuristic universe.
Deep inside old planets' crusts lies precious crystals. Your goal is to go down in sublevels mine with a big plateform elevator. Plenty of monsters will attack you, so you have to build towers to defend yourself while the core building gather crystals.
Each floor is harder than the previous, get the deepest as you can !
To build a tower, click on the icon on the bottom of the screen and click on the plateform.
To upgrade a building, click on a building and click on upgrade on top left of the screen.
You must protect the Base building:
There is 5 towers :
- Canon tower throw a projectile that explode on touch, affecting all enemies around
- Mini turret fires ammo that directly affect an enemy
- Electric tower fires a strike on an enemy and touch enemy around, creating a chain reaction
- Shredder affect all enemies around the building
- Heal tower repair the tower around. It's an ephemeral building, it loose PVs while repairing.
Kill enemies to get crystals, blob are pretty easy to kill, spider robots will drop more crystals.

Wow this is awesome! What a cool tower defence game, great job getting such a goodlooking fun game in the time limit! The game bugged out for me on level 2 but it was still fun! Great job!

Cool, but it lagged on 3rd level and I've stuck

I really liked this a lot! Instantly understandable, controls felt snappy and everything was responsive. My only complaint would be when having tons of buildings and enemies on the screen, everything showing just a green glowing health bar it was kind of confusing to know just how many enemies were there just at a glance. But other than that, this is really cool!

Congat for this classical tower defense ;)

Awesome! I didn't get the bug/lag that other people are talking about but I did find out that if you don't click the "go to next floor" button, you can upgrade and build without spending. Breaks the balance but it makes for really fun enemy blasting haha.

Wow! Only one comment? What a shame. I played it for almost 15 minutes. The longest I played here for sure. Great visuals and the gameplay was engaging for sure. One tiny tip, re-clicking to upgrade can improved. Other than that great entry!

Really fun I like the persisted layouts, I'd like to see upgrades change a little. small bug on the go to level screen tyou can build towers for free :D great fun though

Nice Game. The UI looks great! The graphics and audio are great, too.
Just some minor things I would improve:
- Different colors for enemy health bars and/or shorter health bars. It gets a bit confusing later on.
- Balance. For me it feels like the shredder is just superior to the other towers. And the game felt a too easy in total. combined with the length of the game i lost interest after the first 10 levels.
After all a great game! Well done!

Great lighting effects and models, and I love the level transitions. The game ran very smoothly for me, and it was very quick to pick up. I do wish there was more strategy involved, such as the Electric Tower doing more damage to certain enemies, etc. Right now it just feels like every tower and enemy is the same, and since you keep the same towers as you progress it feels repetitive and not very challenging. Very stylish atmosphere, great job!

I've played up to lvl -8, my thoughts:
Adding building prices to the main hud could help understanding their cost
The game is quite slow and lengthy, a "fast speed" option could be useful
Graphics is very clean, but I feel like turrets could stand out more
Audio is great, love the soudtrack. Mini turrets sfx can be quite loud and in the front, making it quite annoying after a while. The explosions feels rgeat though !
I had fun, but I don't have the patience to go to level -100 ^^

Really nice entry, I loved it! With a little more hints on the costs/rewards of things it would be perfect. Unfortunately I had to stop when I got locked with no more mobs incoming and unable to go deeper =(
Tower defences are always great =D

I love tower defense game! Great job in terms of visuals and sound design! Really satisfying for both watching and listening.
Unfortunately, the game bugged at level 6 for me. No error message. Opponents just stop comming and the game doesn't progress to the next level. Nevertheless a great game!

@zimny11 Hello, thanks for your feedback and congratulations for your well organized base ! We made an update to fix the pathfinding issue where some monsters can be blocked so the level can't finish.

besides the path issues mentioned above, this gave was a very polished tower defense game. i liked the upgrade system too, it was a nice touch. nice game. thanks for making it.

Very funny little strategy game, there is just a bug when you buy or improve towers at the end of a floor, you can buy almost endlessly.
This bug affects both versions of the game, including the updated one.

Great tower defense game! Nice to have so many tower types. Graphics are pretty awesome, but rather dark on my screen. Sound is very atmospheric, but the mini turret sound becomes kind of annoying after awhile.


Well done, this is awesome!
It would have been nice to see the price of what you were buying before you buy it, but other than that, I thoroughly enjoyed the engaging gameplay.
Keep it up!
