TowerFall Ascension on Steam. Its a brawler for up to 4 players where you shoot arrows at each other. The games a lot of fun and the rounds are exciting and quick so you can play for a bit and get back to work. Also you can make gifs out of the last kill in a round, which is really cool.
While playing my co-workers and I talked about how fun it would be to make a 3D version of the game. So for fun I make this in a few hours.
