Really fun and interesting puzzle game with unique mechanics. Clever how the iron bars block the ghost's passage since historically iron was believed to be harmful (or at least impassable) to ghosts and the such.
Couple bugs I found:
- In one of the levels (4 I think it was? Lots of book cases to the right and multiple gates to pass near the top, spike pit in lower left) I had two skeletons near each other and when I went to possess one, the game had me possess both at once. And, when I came out, I had two ghosts. Somewhere I accidentally killed one of the skeletons in the spike pit but it didn't reset (because I technically still had the other ghost) basically soft-locking the game on that level until I reset.
- The exterior walls are passable to the ghost letting you drop out of the world resetting the level (learned this by accident when I was near the end of one of the levels).
