I liked this game to start with, but no matter what I try, it always eventually ends up as me running in circles waiting for mushrooms to spawn while a million melee guys swarm behind me and more and more fireball dudes appear.
The mechanic of the player dealing damage damaging themselves is a hard one to pull off nicely, and I don't know if this was it. But it would have been okay if it hadn't been for the fireball casters. I hate those guys -- they run away (and scatter in different directions in a group), run pretty quickly, can run off the side of the map, do a lot of damage, and have weirdly high HP pools . It essentially always ends up with me not being able to handle them fast enough.
One of the comments below seems to suggest that jumping is an attack of some kind? I think I got a 10 damage thing once, but I could never recreate it, even when landing in a swarm of enemies, which I would expect would remove any positioning problems I could have had. Maybe if I had figured out how to do the jump attack, things would have gone better for me.
Anyway, this was a nice game with a dash of humour; I just couldn't avoid getting to a frustrating portion eventually.
