First 2d Platformer

One reason I started to program was to make games. One of the simplest types of games to make is a 2d platformer. I was able to make 2d platformers in unity but I wanted to make it all from scratch. Unity deals with rendering and collisions but I wanted to figure out how it worked. That is why I made this 2d platformer. There are a few flaws such as having no delta time so the framerate directly impacts the characters movement speed. Playing on a low framerate is like playing the game in slow-motion making it way easier.
