Yes, pressing C isn't very comfortable when controlling with WASD, but normally in the game you dash with the Shift key anyway; it's only in the WebGL version that you dash with the C key. This is because when I first built the WebGL version, the Shift key didn't work, so I later changed it to C specifically for the WebGL version. If you download and try the game, you'll see that you need to use Shift for dashing.
Thank you for your feedback.
