It took me a few tries, but I finally beat it! I think some background music would do wonders for this game. Also, the bomb toss is really hard to avoid, so you mostly have to hope the boss chooses weak abilities to use. It hardly threw the bomb at all on the fight I was finally able to defeat it on. I think the shield was meant to be the counter to the bomb toss, but the shield would randomly not work for me.Making good boss fights is very difficult and for sure an ambitious goal, so good job on putting this together! The UI could also use a little bit of work, and I think the controls should be in the game somewhere. I think if you work on these points, and maybe add some more bosses, I'd love to come back and play this game again!
