This is game is super cool! I had a really fun time with it, though I found kinda stupid when I lost most of my lumps because I was trying to wake them up when actually they were dead. But that doesn't need fixing I think, you can learn by yourself.
The artstyle is great! Just the city scenery is a bit boring to me, and the fact the whole game is on a straight line, maybe there could be some curves in later levels!
But It's a very impressive project! I'm excited to see what you'll do with it
