idk how to call this thingy but it's basicly a game / simulator of earth terain made using perlin noise which i used this to create: https://stackoverflow.com/questions/8798771/perlin-noise-for-1d and you can create bombs by clicking and they will fall and change (maybe destroy) terain
it still got some bugs like in every 1000's x it's wierd you're thinking: it's not 100% pen there are buttons at the start menu, but those are actully drawn by pen too
