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.
