If you play Slope Run, you can explore the space tunnel that connects the worlds in the universe. Get as many points as possible by getting a ball to roll as far as possible. You can see a bunch of brown tiles that aren't stable and it is impossible to jump in the tube. You must move the ball from one tile to the next to avoid the big jumps. You must control it to jump to a different tile immediately if it falls on an unstable one. There are daily, weekly, and monthly leaderboards for this game. Try your best to move up the leaderboards.
