So if I do a speedrun I should probably play the updated version, correct? Also, where can I play it?

Edit: The leaderboard just updated for me and now there are a lot more runs, no idea why they didn't show up before. Anyway, seems like your run is on the original version, so I'll just play that. Thanks for responding btw!

Level 16*

In the world record run, the small balls keep bouncing, but when I play, they just fall to the floor and roll. Why is this?
