Already shows more promise than recent sonic games XD
The controls are real slippery which does make control very difficult. I had most my luck controlling the character with the mouse instead of turning with A/D, maybe add an option to increase mouse sensitivity so players can turn quicker just by using the mouse. Also maybe instead of A/D turning character, it makes them lean left/right, so it's not such an aggressive turn.
Graphics are killer, lots of polish put into visuals, it looks really good!
