Well done! I think this is the best implementation of the rewind time mechanic I have seen so far!
I would recommend to use a cross in your crosshair instead of a circle to make aiming just a that easier & the parkour was kinda annoying to get through as the blocks o jump on where to small and it didn't trigger the ground layer all the time causing me to not be able to jump while standing on top of it!
But once again that's all the developer really shows a loooooot of potential, well done!!
