The controls always being listed with both keyboard and gamepad controls was mildly confusing. Like, I'd always have to put effort into ignoring the keyboard part to just focus on the gamepad part. When I was being given tutorial prompts fairly often, it's a little disorienting. Also, the attack bindings on gamepad seem to be broken; when I played, just using the mini-hakkero and throwing a potion were bound to the same button, which meant I was throwing potions willy-nilly without meaning to, which made combat a nightmare (since I kept wasting my potions AND my attempts to just use the mini-hakkero kept getting blocked by potions AND I wasn't sure if the fire would hurt me so I kept manuevering around it). I just assumed that was how the game was, but then I read the controls and realized that they're supposed to be bound separately.
Besides that (and the obvious and deeply understandable problems caused by this game being extremely unfinished), it was a fun little time. The Cirno/Wriggle relationship drama was cute, and Wriggle's "favorite show" got a genuine laugh out of me and my friend I played this with. The mere concept of this game being a Castlevania 64 clone was also pretty nifty.
