Reminds me of the old text terminal games, snake and worm, but with better puzzles. :)

It doesn't really need to have die-on-collision with the puzzling walls. It'll be a pain when I'm tired.

I think the scrolling issue is fixed. At least, it works for me in Firefox.

Sound loop is a bit short, I had to mute it quite soon.

Playing field is a tiny bit too large for my 1080p screen. I had to zoom out one notch. Not really a problem as such, I have to zoom in or out for every game on this site. :)
