A really cool concept! I think I broke the game on the fourth level as I was controlling both the ghost and the player at the same time. This game has a lot of potential, though, and the puzzles I was able to do have been pretty fun. Nice job!
Yes we know about that bug… The way to fix it is to kill your “alive body”, then take a teleporter with the ghost. We didn’t had time to resolve this. We are happy that you still liked the game, thanks!
