This is a 2.5D pen platformer engine. This took many hours of work, hope you enjoy. This was also a test, and well, a successful one. Remix to make your own platformer! All info is in the project. 2.5D means that it is 2D, but has a 3D effect.
This code is 90% by myself. I came up with how to make it 2.5D, and please don't think this is using @-RISEN-'s 2.5D pen platformer engine. I only took inspiration from him.
