Nice little game. Easy to understand, and simple - but clean visuals. Levels are balanced throughout the game, and have a nice difficulty curve. Soundeffects are great, except from the popping when you play one sound over another, but I guess that's not what you want to prioritize with the limited time. :P One thing I would do is making the square that the player controls, stand more out. I see the green arrow over it, but it took some levels before I got used to how hard it was to spot. And i encountered a bug at the final level. The two black shapes in the bottom and top right corner won't trigger when i stand on them, and I can't finnish the level. :/ But overall a very good game. Well done :)
