Super Freaks 1 Ultimate Edition (Pre-Alpha 28, Elastiband Pt. 1)
Introducing the single dumbest feature in this game: the Elastiband, inspired by the Knuckles Chaotix ring tether.
I consider this an improvement over the Chaotix tether for two big reasons: one is that it's optional (both players have to switch on their Elastibands, currently mapped to the X button), and more importantly, you don't get wildly flung all over the place. This version of the rubber band mechanic lets you drag the other player around, and hang below them when they're standing on a ledge above you, although there's still just a hint of the wild elastic physics Chaotix had to make it more fun.
I'd say the Elastiband is more helpful if you're playing with someone who keeps getting left behind--this should help them stay closer to you. I might play with the physics and stuff still, but I'm pretty happy with how it feels already.
