this is a platformer template packed with all of the necessities: momentum, wall sensing, gravity, ground sensing, and obstacle sensing. (sorry, no actual obstacle sprite included!) once you remix it (yes, please remix it instead of downloading the project and pasting it in your account) just make a sprite called obstacles and use that as the, well, obstacles.
this is like a mixed-up platformer code; 50% goes to @griffpatch, 40% goes to @minecraftpuppy, and %10 goes to me. wasd to move, remixers. also, see: https://scratch.mit.edu/projects/623384165/ shoutout to @tocino1305
