I've spent the last 3 years on and off in spare time working on a 3D platforming game with my buddy Alec Smith. It's only a single level but with everything we wanted packed in and polished up for players to enjoy and it's not available for free on Steam. Along with the game, I also created a cinematic trailer to help promote it and capture what a platforming experience would be like in a film sequence and ultimately give context to the world our character exists in.
