Miziziziz's simple platformer ported to Godot 4, made for this tutorial: https://www.youtube.com/watch?v=NScngW8vxK8
The controls are admittedly a bit wonky, but it works. The collisoins are also a bit weird (only the top collides correctly). I may open an issue about this later.
But it mostly works and I'm tired of working on it lol.
UPDATE: I accidentally deleted everything and lost all my changes. So I had to redo everything. I guess doing it twice reinforced my learning a bit. I still don't know what I'm dong lol
