    Love all the games here, but Sonic Masters wont load the levels properly. Despite that, this is a great platform for 3D Sonic fangames. Vastly better than Sonic Blitz in my opinion.

      Thanks for leaving your opinion.

      Sonic Masters works for me, I can load all levels… wondering what’s the problem.

    I really like this one, everything about it is done very well. The only problem I have is that there isn’t many different enemies to fight.
