I'll always be a fan of small, experimental games that isolate interesting core mechanics. Hope you keep going with the project. Some critiques:
- Game felt clunky at first, even for someone with a bit of smash experience. More visual/audio feedback for player actions may help this.
- Tutorial could use an example of what proper wavedashing looks like and perhaps why it's useful (or just make another youtube video)
- Needs a training mode! Just take away health bars and let people keep smacking each other uninterrupted.
- Lack of shield and the addition of walls really change the flow of the game (not necessarily in a bad way). I'm interested to see how this affects strategy for high level play.
