Rain Runner is a short, blood-pumping speedrunning FPS where you ditch your keyboard and only use your mouse! You'll run constantly where you look, shoot targets and dash through challenging platforms. No checkpoints, no pauses: beat it in one sitting! Run, die, learn, repeat. Be better, be faster.
Its pretty fun, I do wish there was more content but it is fun and I think the idea is fun if there was a lot more content there would probably be a bigger fanbase and I really hope they update the game.
