Hi Sebastian,
I could not go very far in the game as I had crashes each time, that seemed to happen on collision with various objects from the house. A bit disappointing as the game looks cool and I love your work, so I'd like to know if those issues are just on my end, or if you're planning or debugging a bit? In such a case, may it help to send you the crash dumps or something?
Anyway, I'll try playing on another computer when possible as I really want to catch those bugs!
