The video settings aren't loading on browser on purpose. If you're playing in the browser, set a very high resolution, and don't play in fullscreen, the window ends up misaligned, which makes the game look bad. For now, I have it forced to windowed mode at 1280x720p. (I should really disable the fullscreen option in the browser build so players don't feel like something is broken.)
The game really isn't intended for fullscreen in the browser anyway because pressing ESC exits fullscreen mode. I'm going to disable that option until I can fix all these issues.
Keybinding is on my to-do list; I'm well aware that every game should have it.
