Couldn't figure out how to go fullscreen, or why the gun didn't seem to do much, am I missing something? The screenshots look better than what I got to experience, sadly. I did like the cute pixel art and lowfi Christmas beats tho.
Edit - I tried another html 5 game and that had a fullscreen button in the bottom corner, so I retried this to see if I missed it, but there definitley isn't a fs button that I can see.
