Hello, I have encountered a soft-lock glitch in the mansion.
There is a part where you need to start 4 generators to power-up an elevator. In the room of the 4th one, there is a huge block that can push you down a hole that sends you back to the first floor.
I happened to get caught by this enemy after throwing a bomb on screen, bomb that was not taken by the block (it was further to the right, next to those ghost-like enemies). As a result, I fell back to the first floor, but since I had thrown a bomb, I couldn't use the Bomb spell any longer!
I tried quitting the game and relaunching my file, but I still couldn't use the spell. I managed to reset the variable by going into the save files and setting the "bombs_wait" variable back to 0, but I guess the situation could happen if you exit a room while a bomb is still active on screen?
Anyway, I wouldn't recommend saving the "bombs_wait" to the save file as I do not really see any case where it would be helpful to save the fact that the player just threw a bomb :)
There also were a few instances where the spawn location after using a ladder to get to the underground part of the castle weren't the right one: the first time I exited the place I returned to the room with the clock, and at one point using the ladder from the top-floor made me appear at the wrong ladder in the underground. Nothing ground breaking, but just to let you know!
