I heard that the Combi-ring was in 1.09.4, but got removed. Would it be a bad thing to put it back? It'd probably be really fun to use, especially in a coop game with many players. The characters don't have to have any ring holding sprites, just that beam of sparkling light should hold them together like in Chaotix. Each player could choose a partner to play through the level with. Except, with no team attacks and holding launches. Also, for situations such as spindash caves, players should be able to press the ring toss button to shoot back to their partner (Allowing them to go through walls of course), but only 1 of the 2 partners should be able to do this at a time. When one player dies, the chain breaks until the other catches up again and bumps into the other player, then they get automatically combi'd again.How could he Combi-ring be activated? By cheats of course. In the console, the admin or server could input "combi Iceman404 to Player 3" which would link the players together. "Combi off" would disable the combi for all players immediately. I asked many people this in the Standard, and Casual server, and they all agreed it would be an interesting feature to add. Except, if it's even possible to do in the first place.
EDIT: By the way, I know the rubber band physics aren't possible.
