I do kind of agree with this one, yes. Also possible is per (say) 5 levels there's a checkpoint? Although it is an astaetic to have to do it all over again.
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?
Super cool game! For me it's a whole new sort of tower defence (ish) game, whitch I really like! Btw, your art is nice, kind of retro. Are you considering new uptdates or even a full release?
