Q1K3 - An homage to Quake in 13kb of JavaScript
Nice, i actually played through its two levels twice (they are simplified recreations of the E1M1 and E1M2 though the second level has a few differences).It is interesting to see how the levels are basically made up of axis aligned cubes which simplifies collision detection and response considerably.The textures are also made using procedural generation using a tool (and library) the author made[0]. I think a "blur rect" and "blur and map result to existing colors" would help a lot with the aesthetic. Also the editor would benefit from a "duplicate step" option too.[0] https://phoboslab.org/ttt
