Mhm.. Ye, understandable. If i can still give you some feedback...
- ...I'd had made the grab and the throw button more closer (let's say Left and Right Mouse Button), Or at least all on the mouse/keyboard (it's really hard to switch form the keyboard to the mouse just to throw the bodies)
- ...I'd make a reskin of the "stalactite"object: maybe a piece of falling roof, or maybe even a proximity laser that fires you if you get too close. As it is the "stalactite" is only weird and unfair to the player
