Hey, I hope you're feeling better; getting sick during a jam is just awful.
Visually, your game is already impressive, and I believe you've made a good start here.
The controls take some getting used to; sometimes my character just jumps up, then again, and again. For noobs like me, it would help if the bosses somehow gave small signs of what they're about to do, so I'd have a chance to dodge, run away, or stop them with an attack. Unfortunately, I'm failing miserably.
