WASD to move and jump. E to Steelpush. Q to Ironpull. Move your mouse to change your target anchor. Click to throw a coin, which becomes an anchor.
Inspired by @04tmoody , who coded a different Allomantic metal (Atium) Mistborn, a series written by fantasy author Brandon Sanderson, has a magic system where you can ingest metals to gain different effects. "Burning" Steel this way allows you to Push on metal (The object moves away from you if it's lighter than you, and you move away from it if it's heavier than you.) Burning Iron does the reverse, Pulling yourself towards an object. Here I've coded it into a platformer engine. The actual movement engine is made by @griffpatch . I probably could have coded my own but I wanted to get straight to the mistborn bit
