Hi! took a couple of tries at the boss but couldn't beat him lol.
I really liked the music you used for the boss fight. The mechanics took a bit to get used to. I was mostly using the explosion so I didn't really use the other abilities as much. I like how the alchemy circles show up for the shadow abilities too. It would be really cool if it had a platforming level before you reach the boss, where you get to use all of the abilities.
Overall, great job on the game!
