I like rats in video games, so it was cool to see them there. Also the candy that you can pick up looks really cool too, I don't think I've seen that kind of candy in video games before, and I have some good memories related with the candy of that shape, so it have put a smile on my face.
I wish there was some kind of ambience audio playing, as the sound effects of things happening are only that and the rest is complete silence. Overall a fun and interesting little game, I hope you'll continue working on it!
