I like the spell upgrades the cover art and the color palette. For me the spinning was very dizzying and was bascially a time to not move as my move would be basically dangerous to do. I think tweaking that would improve the game. Also I think the hp of the enemies is too much, I basically will have a lot of vertigo before finishing off enough enemies, which for me was not clear when (meaning after killing how many enemies) a wave ends and the other begins.
