I liked the music, simple but enjoyable. I liked the concept of the game. It was a neat idea but flawed.
I got stuck on the fourth(?) screen, the one where you had to climb back out of the pit.
I thought I was coming close to a solution but then I’d get stuck again and the reversing mechanic seemed inconsistent at best. Took me awhile to even figure out what could be reversed.
Also, everything also had a very floaty feeling to it which made things hard to control.
Overall, not bad for your first game.
Keep it up!
