Space Cat is a 3D rail shooter. It's free. No DLC, micros-transactions or anything else. I made it because I like this kind of game and there other people weren't making them anymore.

Play through a short (< 10 min) single player story. It works best with a controller, but can be played with mouse + keyboard as well.
