I just thought I'd say that I love someone appreciates the Sonic comics enough to make something like this game. Most people only know about the Sonic games and, those who do know the Sonic Comics, think everything was Ken Penders. There is just complete cultural erasure of all the great writers and artists the worked at Archie on this wonderful series and the artists who continue to do an amazing job at IDW.
I've never heard of the Charge system before but it looks pretty damn cool. Seems a good fit with its momentum based mechanic.
