I was *planning* on having this be a compo entry, but I was struck with the fury of REAL LIFE and was unable to complete it in time.
I had never made a puzzle game before this, and now I know why. Not a fan of designing puzzle games, which is why I only made four (frankly terrible) levels.
The graphics work well, but the game is very short and I feel like the concept wasn't explored enough in the level design, which is a bit like you said.
Loved the minimalist graphics. The mechanic was really cool and it left me wanting to explore all the ways you could use them. The game ended just as I was getting into it.
Too short, and movement is sometimes stuttering. Other than that, the basic idea is an opportunity for level design practices, if you have the time to do more levels. Keep going.
Very clean design, reminded me of those old games that you can buy in vending machines. (I can't remember what those are called for the life of me). I liked the style of it the most, some SFX would have been great and more levels would be awesome. I think this game could be extended a lot into something really awesome and I'd like to see more. Nice one! :)
Puzzle design is hard, i have tried myself, and you never know if it's obvious, simple, or hard like hell.
The game is simple but powerful. With a good puzzle designer, you could imagine many many levels, even a procedural way to create them.
Actually the idea is better than many "switched world" that i have seen for now.
This kind of game could keep me for hours! :)
