WASD, arrow keys, or mobile controls. Space works to jump. Remix if you want! Just remember to give credit :) Please do not report, I just moved this from my main account to this one. WARNING: This is an engine, not a game :)
All code by me. How I made it: I started with the engine. I wanted to use the engine I normally use for platformers, but I had to make a few tweaks. I didn't want to make one of those platformers that are super complicated. I also didn't want to have the variables multiply by -1, but ultimately I had to. Then, that was kind of it... :)
