Leaked Sonic the Hedgehog 4 Footage
From this footage you may notice a few things:
There are 4 Zones + Special stage (Splash Hill Zone, Lost Labyrinth Zone, Casino Street Zone, Mad Gear Zone).
Sonic still likes to shake his finger.
Spin dash is in the game.
This is an “alpha” version so the gameplay still looks a little rough, but hopefully by the time this game is ready all that stuff is ironed out.
