Haha fun review to read :D sorry to hear you didn’t get to the last lever. It does require some platforming though for sure. A sneaky tip, when you’re in the big tower room, if you go to to the floor where you turn into a ghost, drop off the side and hold left to get back into the halway, you can then take the stairs all the way to the top where it’s a little easier to jump across to the lever.
I’m glad you enjoyed the game. And yes, our heroic spirit walking character is willing to suspend all disbelief and take the realization of a machine that turns him back and forth from ghost to human all a days stride. We could all learn a lot from his reckless abandon :D
