Nice work! I like the graphics and the game has a good mechanic! I think I would prefer to increase the player movement just a bit but that's just me. Also, I found the rewind cube a bit buggy, where it wouldn't rewind all the way. (Or maybe I didn't do the puzzle right)
Anyway, nice job! The puzzles seem well executed and with a bit of polish, this could come out really well!
I made the rewind cube to go back at a fixed time that is 5 seconds. So, at the end of the 5th second, it might be that the cube may be upright with just the edge touching the ground. I have turned off the physics, so gravity is not much of a factor for the rewind cube.
I plan to polish this once the jam is over. I've got a few ideas on what to implement too. :)
Thanks for the feedback.
