Exactly what it says on the tin.

Crash in this room while using hook and super jump and about to enter the room above:

I found quite a massive bug (hopefully very easy to fix) : If you pause the game while an enemy bullet is on screen, the bullet animation don't stop, go through everything without damaging and disappear. Quite a way to cheese some boss haha (works on last Maya encounter + the explosion of the smoke-like mob, not all enemies in fact)

I'll continue messing with pause menu and frame perfect inputs for a bit

PS: I don't remember if I also mentionned in the final questionaire the Pistol quick-firing one time out of 3, even when waiting between the shots

Found a place where you can use the grappling hook on rock walls :

This can only be done while jumping as it seems
