Arrow keys, or WAD.
Made my old project better. Thanks, @easqs2qawdrsfrxrscf, you necroposting on a super old forum post made me entirely recode my old game. Changes: Switched the stages from the backdrop to an extra sprite, changed thumbnail, changed code and how the guy walks and jumps, changed one stage to avoid getting stuck, that's all I can remember. Go play both to see the difference!
