Very stylish and fast, with a somber Zero-like story. Also incredibly easy. Finished my first playthrough with Hazel in about 40 minutes... though that could be faster, cuz the general feel is if you hold right and jump off the edges of platforms you can usually tag > dash to some higher area and just keep going. Parry timing is very generous, dash attack seems to give some invincibility, and if you figure out tag > dash attack > double jump tag (or just tag if the hit box is big enough) you can just chain attacks together and kill bosses very fast. Will go back and see what Axel's story has going for it, and kinda hoping if I S rank everything there's more to it, but these indie games do trend disappointingly short.
Anyway, fun and worth a play.
