I made a system for rendering tile graphics and a simple tile set, and I wanted to test it, so I used some basic perlin noise to give it some data to generate with. Turns out it's a fairly decent level generator! Cool, huh?
The generation goes forever (basically).
space switch tile set
+/- change the scale of the generator
e export to a png file, if you so choose (make sure your file name ends in .png)
