I really enjoyed the last two bosses, I died multiple times but kept going until I finally won. It took me a while to realize that the only way to die was by staying in the darkness for too long, and I didn’t notice any differences in the activation runes. The music is fantastic, and the game is fun, but it could use some polish, especially regarding the screen/camera size, as it was hard to see during the final fight, and possibly the player's size and hitbox.
