Combat is turn based, pressing space more then once per turn may be the reason it's braking. Unless you're not doing that.
The elevator one does seem to be a bug.
The one with the weird creatures seems to be intentional. The clue does tell you to hide when it spawns. Not sure if that works since I've never bothered to hide.
The wind spell only has a chance to work, look to the left of the screen to see your resilience, that's the chance you have for it to work.
