Max is 2 players Scratch needs 0.1 seconds to send the online variable to all the players, so if you are playing, the best ping you can have is 100 which is a bit unfortunate, I cannot do anything about it since i am using only 1 cloud variable, if it was 2, your ping would be 200. @dragon_king_the_rell for the online engine Arrow keys to move You always get smalle Pick up circles to get bigger Touch the other player to make both of you get smaller Green circles give you 0.6 points of size Purple ones give you 1 Blue ones give you 3 Red ones give you 15 The yellow ones with arrows (Boosts) on them make you faster (2 seconds) The light blue ones with a snowflake figure on them freeze your size, so you can get bigger but not smaller (1.5 seconds)
