Dwitter jump and run, literally. Use arrow keys to run and tap to jump!

u/KilledByAPixel

That's really cool, mini mario! maybe it would be smaller to put jump on the up arrow key
u/username

it would be, however, it would not be possible to hold down an arrow key and jump at the same time and that annoyed me a lot

Can someone explain why the circle becomes a rectangle?

u/Tesseract

After the first drop, the vertical velocity takes the same path for all points (begining at -9 and increasing by .2 each frame). However, the horizontal velocity is pushed towards a fixpoint of v=v+sin(v), either at pi or -pi.
