Use the left/right arrow keys to move, use the up arrow to jump. Click that green flag to start, and don't forget to hit the stop sign if you want it to either end/restart. This isn't really a platformer, but it's also not not a platformer, if you know what I mean?
The sound effects and short correct/incorrect jingles are from the Scratch sound library. I made the main screen melody & the song heard throughout most of the game using BandLab. Sources: dude just trust me (I may add my list later/include one in a sprite inside, but I'm crunched for time right now)
