I will not be at GDC for lots of reasons, it's hard and expensive to travel from Brazil to the US, I didn't plan it in time, but here's my game, Slipstream.
It was funded on kickstarter in 2016 and after two painful years of struggle, my team consisting of 2 people, me and the music guy, managed to release it. A few months later it got a big update with local multiplayer, new game modes, bugfixes and balances.
It's a pseudo3D arcade racer with drifting mechanics, inspired mostly by outrun, sonic the hedgehog, initial D and vaporwave. Here's the release trailer:
