It's a fun game, best for luck for the release.
A couple small things:
1. The menu where you choose between Low- Ultra quality graphics could use with some color highlight on what option is being selected.
2. The controls are a bit buggy if you have both a keyboard and a controller plugged in. I can't dash with L Shift with a controller plugged in, and I can't reset with a controller.
3. Could definitely do with some additional input when the player gets hit. Not sure what is best but a sound effect and a little bit of rumble on the controller would be great.
4. I rolled off the 1st smash all the targets stage and I didn't die. It was with a dash where I took an enemy out with me if that helps track down the bug. I could reset but there was no 'git gud' screen.
5. With Pic below i dashed into the following direction into that box and fell through the world.
