I feel very frustrated because your game doesn't explain the mechanics very well and controls are not rebindable. You should be more accessibility conscious when making games.
I am sorry you feel that way. The game is simple enough: left, right, jump or stay still. Hit-hit-hit or block. That's it. It's a simple game inspired by arcade games from way back. Sorry we couldn't add rebinding or a tutorial, we are a small team and our resources are very limited :(
