However, the character still jumps too low for me, and you can make the dash longer. I remember there was self, a game on coolmathgames similar to this one, and the dash was big compared to the jump. (https://www.coolmathgames.com/0-self)
We started with the player having scroll to, but when it got to the edges of the map, the dashing was messed up as the player moved without the camera.
