Nice music, art, and visual effects - as you've already noted there isn't much in the way of being able to play at the moment. It'd be nice if there's an updated version for there to be some sort of "practice moving" tutorial level, and perhaps even ability to rebind keys (for those like myself unable to scrounge up a player2, the arrow keys are too far from wasd for the keyboard char to be able to shoot while also using the mouse :D ), before being dropped in. Definitely understand that was out of scope though.
Thanks for the experience ^_^ Cheers.
