THIS ISN'T A GAME OR PLATFORMER ENGINE! if you want a platformer engine, go to my profile and use my slope detection platformer engine. press Q or W to change size
When making a platformer, keep your players small! making players too big stops you from adding new fun things to your levels. a size of 15-30 is good, but i sometimes see games that are around 50 or even 60, which removes room to add fun or challenging levels.
