About Uprunner
Uprunner is a free-to-play MMO vertical speedrunner that you can play in your browser. Win lobbies or make your own maps to get Coins, which you can use to buy random skins. Use all of your skills in UpRunner io to win the battle.
This is a great game! I would change the setting to stop iFrame from scrolling, since the arrow keys keep moving the game by themselves.
