I likes the idea and the general presentation and vibe
But I feel like this was just the starting, the idea has alot left to be explored
The mechanics of the body following its ghost and the rewind are reallly really cool, but dont get used to their fullest potential
Another thing I noticed was there was no limit to how can u can go in ghost mode, after the "Good luck" msg, I just went ahead with the ghost and then missed a jump and fell into the void around the end but the ghost didnt die. I couldnt see the ghost (it was off screen) but I could still control it and just walked to the end skipping everything
The Ghost mode, body follow and the rewind mechanic are very well made, they just need to be used more
II do wonder, will u continue development on this further? Id love to give future versions of this a try!
