Brutal in difficulty but addictive, might be improved by having the rewind mechanic able to flip the levers as well as push the buttons, but that might just be my inexperience at these sort of games more than anything else.
Really good fun
Your ghost is able to flip levers and push down buttons. However the puzzle is made in such a way where you don't need the rewind mechanic to actually finish them. Which is honestly a bit of a shame. The potential for the level design is there but I just didn't have the time/inspiration to come up with something that both uses is it as it's main puzzle mechanic + is easy enough to follow and understand.
