I decided to make an adventure game engine + a game for a school project. I ran out of time so I never got to finish the game, but the engine itself is working pretty well (still missing a few key features).
It's my first 3D engine so I'm immensely proud of it still. MAN, WAS IT HARD!!!
I may make a real adventure game out of it someday.
Development time: 2 weeks
Tools: C++, Blender, Photoshop.
