Nice little game. I really like the design idea. It's like an old-school platformer where you can't go back mixed with a scrolling shoot 'em up. I like the little mushroom guys too.
A couple bugs:
- What's with being able to walk off the screen? There's a bunch of places where you can walk out the side of the level, and I guess you can always walk down out of the screen.
- I also hit a bug with the boss. I died fighting him, then on the second try it gave me the "Congrats you win!" screen when I was only part way through the fight (where the round shooter guys start spawning).
