I liked the abstract world we were in and the nice soothing color pallete. The music was also very nice. Everything really contributed to a nice abstract sort of feeling.
You designed some really good puzzles, and it was always satisfying to solve it. But sometimes the solution seemed to just happen? Like I'd sit on a magnet, and see other magnets pass me by and I'm think "ok I got to time it so that I can get to that one" and while I'm thinking I just am taken to the blackhole its like oh...okay.
Also, I don't see there being much of a point to the lil machine in the beginning.
Still, very fun game and very interesting concept. Good job!
