Thanks for rating! All the enemies can be jumped on and they are supposed to damage the player, that is why there is a health potion just before the archer in level two. Btw, how far did you get in the game? Like up to what level?
Ahh I misinterpreted the description; I assumed that 'you can walk on heads' meaning you could do so without damage, and I was incorrectttt. Not far! Bout level 3 if memory serves.
