I’ve made an extremely simple FOSS 3d platformer, based on the ThirdPersonNavigation scene in the engine! (I just added jumping)
It’s based on Pepper & Carrot, the CC-BY webcomic. I made almost all of the assets myself in Blender (I only started learning Blender this year, so they’re very basic and the animation is kind of terrible) released under the CC-BY-SA 4.0+ license. Code is under AGPL v3+.
There are about 10 levels, mostly just collecting yellow spheres, but also one underwater where you swim, and 2 where you fly on your broom, and a couple of ones where you throw snowballs at people.
It still has FPS counter and debug information on the screen, because I just got bored towards the end. Lots of code spaghetti and probably bugs (I also only started learning Pascal this year too )
