Just bought the game, having fun so far!
As a feedback, I'd like to have a rapid-fire option for attacking, as I developed a bit of tendinitis from button mashing in games. A quick script from AutoHotKey did the trick, but having the option in-game would be nice :3
Edit: A dedicated dodging button would be nice too (pressing a button while holding up or down instead of having to press up or down twice)
