you almost beat me to my secret project i've been working on for last 2 weeks in silence ;-)
u/rodrigo.siqueira

I want to see your project u/Xen. My wishlist is to use x.drawImage(c,1,0) trick to show infinite horizontal scrolling mountains. I like this style of generative mountains since I saw them for the first time in Moon Lander game, Atari's Vanguard and Moon Patrol.
