I just learned about Wadanohara recently and I've been trying to play it. It's fun so far, but I got hit by a bug somewhere in the Sea God Castle where the game acts like I'm holding down the right arrow key. I can still sort of move if I hold down the left, but at a rate of like three squares per minute.
This is the only game that's doing this, so it's not a stuck key. I don't have any other input devices plugged in. The bug persists when I start a new game. There's no way to remap controls or I'd have tried that. Halp pls, I'd really like to enjoy this game.
