Sonic Advance 3 is a Sonic game with a twist: the player can play with a friend in co-op mode or one of many multi-player modes like ring race. The game contains features from Sonic Advance and Sonic Advance 2, but with more options like choosing from 2 characters in story mode (a leading and a following character).
This run is an improvement of 2 minutes over Dashjump's previous run (http://tasvideos.org/3030M.html).
