I have a bunch of demo projects that I don't have much use for. You are free to use use these projects if you want. No credit needed. I may post more projects in this thread down the road.
The code down below is not perfect. These are just some projects that I scrapped.
Turn based RPG with name creator, menu, XP, health, and random battles (unfinished):
I updated the platformer project and added proper falling. If you are falling, you cannot spam the A button to keep floating. I also added item blocks you can headbutt and tiles you can break.
