Platform game"engine"

These are two "prototypes", or "engines", for a plaform-game I wanted to make with love2d a few years ago and that I had to quit because I hadnt got enough spare time to even design it. Platform_20180427_64bit has enemies too but no player vs enemies collision detection. The scrolling routine moved the background. Platform_3_20190918_64bit is a bit more refined because the scrolling routine moves the camera. Unfortunately no enemies were added, but the player can shoot. Arrows = move S = shoot A...
