The nickname of the best player is shown to everyone at the start - beat the game and your nickname will be displayed too. Change skins to easily tell players apart.

And check where each portal leads ;) Colorful skins and different character models. Pets (cats, sheep, dragons...

they count as pets, right?) If the game feels too hard, activate a boost like double jump or others to pass difficult sections. Checkpoints are not saved - each run must start from the beginning so speed times are fair for all players.
