Decently enjoyable,  the final boss is annoying and the hp they get from boxes, the 'regen' they get when you can't hit them, and the fact you only have one straight line projectile while they get to aim theirs isn't helping.  I feel like the dash could act like Wario's shoulder barge, there could be a ground Pound, give us more options to deal with them, and we could be able to hit the blocks in the first level to regain health and get more powerful flame blasts to take care of the basic enemies.  The second level is fine, but I HATE the hitboxes I could be above him and currently inside his head, but since he's falling i die and he takes no damage.
