I got a bug where enemies are inside of the wall. This made it impossible to move on. Maybe the rooms could open automatically if you take too long.
We're sorry that happened! We were pretty sure it that bug had been resolved. Do you remember which level you were on?
I got it on 5-2, also the purple worms seem to pretty buggy. They basically go behind the level. Pretty similar to the super mario bros 3 glitch.
