Fun little game! Art reminds me of Pseudoregalia or A Short Hike, and the music (and the musical theme!) are solid. Gameplay is also good, though the AOE attack/interrups from Presto were a little annoying until I learned how to dodge most of them.
Not too easy, which is good; I do appreciate that dying does not mean starting from the beginning, though, as some of the bosses required a few tries :)
