Decent puzzles and fun gameplay. Added a little more leeway for collisions might be a good idea. And try to use a color palette since somethings can be harder to see, considering most things are either tone of greens or blue. Definitely a good game nonetheless though, it was pretty fresh and interesting. Keep up the good work!
