I'm working on a 2D platformer but I realized that I don't know anything about designing a good level. So... Can anyone help me? There's 10 worlds, with 5 levels each, but I'm okay with someone who will just make a couple or even just one level. I have a demo of the game which basically shows the most simple mechanics of the game.
Contact me right here or send me an email at firstname.lastname@example.org if you're interested.
