Hey, I played around with the game a little bit, here's my feedback! :D
Graphics: The graphics look nice and clean, not to cluttered, pretty much perfect
Audio: The sounds are really satisfying, but I think music would have fit the game pretty well.
Gameplay: Maybe i'm just stupid, but at first i didn't get the game at all. Maybe make a clearer tutorial next time, because I struggled a lot with understanding the game. Also, I don't understand what the blue boxes do. So tutorials is the main thing you should improve in, but otherwise it was fun :)

I hope the feedback helped you, and it would be nice if you could check out our submission as well, thank you! :)
