I like how this game is a (somewhat) simplistic idea, and how you then went and made some very fun and challenging puzzles out of it!
The only thing I don't really like is the kind of pixely art style (mainly the font), but that's my personal preference. I also saw you said some people didn't read the tutorial text, which might be because the text can be a bit hard to read with the wobbly effect (Maybe just turn it down a bit), or people are just unobservant. Though I did see you said you were having some issues with the font.
Overall I liked it! I also seem to have a tiny bit of a skill issue :|
