This is so freking awesome!!!
Sega should do something like this!
You really improved the difficulty, and Tails Doll's attacks are a lot more eerie than in the first (Really, those attack were too colorful). I also loved the songs, especially the boss battle theme, reminds me of when i played Sonic the hedgehog and defeated Mephiles... It was so cool!
10/10, 5/5, and added to faves, no doubt! >:D
