Hello, I have tried the game and I was disappointed.
I wanted to play because it features Cosmo from Sonic X. I imagined that it was going to be a character focused on magic (a character with high magic stats but low physics stats). And that he would focus on using healing and support magic, in addition to her botanokinesis. Something similar to Aerith from Final Fantasy VII. And that if you had Tails and Cosmo in your party. Tails would receive a buff, becoming a very strong character.
But the character was practically unfinished and with nothing to highlight, making him a very useless character. And that really disappointed me, as this is one of the few Sonic fangames that dares to include characters not only from video games. But also from series and comics like AOSTH, SatAM, Archie, Fleetway, Underground and Sonic X.
