Found an oversight in mario run & spent 2.5 hours to get a score of 6560 but sadly didn't save to the leaderboards.
EDIT:just did it again & this it worked, now i'm #1! If you want to know how it's done, this is how. So if you hit a block you stop moving & if you get lucky 2 blocks will on spawn so that one you stand on while the other stops you from moving. Now while you stop your score keeps going up so it's just a waiting game but why it didn't put my score on the leaderboard the first time is because when you wait the blocks, coins & enemies keep spawning in the same X, so the servers get overwhelmed when you jump into them but how i got my score this time is i jumped on a block then again over the wall of stuff. Hope someone can beat my score sometime using this & i hope everyone has a lovely day!
