The vampires or flying rats end up flying against the walls unkillable, the worms at the begin sometimes are invincible too, another annoying one is when you go "pregnant" to bring monsters to the sister,the character gets stuck giving birth and also becomes immune to damage and can't be moved, you have restart to continue playing, that's everything I've seen so far since I'm only on level 5

This is the last one I played, it got impregnated by a spider and then I couldn't move, I also got stuck when the character got impregnated n she stayed on the floor n I couldn't move at all, the bats crash in a level where there are two stones, I don't remember the number, of the level,I'll check it out later too https://vimeo.com/1079008567?share=copy
