What a errand for a flash drive! I enjoyed the silly tone of this game, and the amount of different character sprites is really impressive! The dragon boss fight is really great, I wasn't expecting a different giant sprite for one of the attacks. Your commitment to having a proper transformation sequence is huge for this jam as well.
I think my biggest piece of feedback is this game is pretty tough. A bit of invincibility after being hit, and a way to heal besides the water coolers would go a long way. It's tough to dodge a lot of the projectile attacks, the screen where you get the double jump and falling through the buzz saws before it gave me a lot of trouble in particular.
Awesome job!
