Not bad really, the tutorial could've done with being in the game i think.
Music was fine, the loop was a little short but it didnt get on my nerves so it gets a pass from me. Art was pretty good! i loved the individual assets, you clearly put work into them all. They didnt synergise very well with the rest of the environment, but i can excuse that for a jam game.
Gameplay was very simple: Put the right boxes on the right buttons before the timer runs out. Which buttons are right? Who knows! its trial and error! I quit when i got to the 4-button level because i wasnt willing to try all the combinations alongside the very short timer. Trial and error of this nature isnt a puzzle - its busywork.
the time rewind mechanic seems inconsequential: you press R, then you reset to the start of the level with a very slow animation. I always preferred to just die rather than use this. It truly seems kinda tacked on - the game wouldnt change with its removal.
As-is, the game is a competent display of pixel art, and a just-fine display of game and level design. Just, please steer away from trial-and-error puzzles in your next game
