Good game, the movement was clean, the visuals were simple but precise, and the levels were short and straight forward. The rewind theme was very well done and done in a very literal sense while I had trouble realizing what your exact approach to the out of reach theme was to be. If you wanted some critiques I only have a few to give and mostly on the animations themselves as the game itself was fairly solid and fairly well done. Animations of course arent the most important aspect of 7 day game jams, at least in my opinion, but every bit helps and were all here to learn. In my opinion, the professor's idle animation is too fast, simply adding duplicate frames, changing his frame rate, or adding more frames with smaller adjustments would help with this and the exact approach you would want may differ engine to engine, artist to artist. Additionally the player's walk cycle seems to be half of a walk cycle as opposed to a full walk cycle; so if that is the case then you did half a walk cycle very well but if its not the case then you might want to look into ways to more clearly articulate the walk cycle's switch from right side dominant to left side dominant. Anyways, good game.
