After 2 hours of straight gameplay and many many tries, I have finnally beaten the game (I think). I'm on the nineth floor and I cannot find another staircase. Thinking about it, I killed this teleporting man, have I just won withouth knowing it?
Well done! There’s a bug where the victory screen doesn’t trigger if the Lich King dies by spikes. Probably what happened. Sorry about that!
I think there should be an endless mode if you can develop that.
