Ok, people have been expecting this for quite some time, but it amazes me how Sega have managed to keep this so quiet.
the game itself is just a port of the classic games this touch controls. it isn't flawless, it does lag at some parts in the game.
Also the price £3.49 it just a little bit pricey to be honest, i mean its not a big game like say Myst so really they could do with bringing the price down a tad.
Overall game play is good, like i said it does lag a bit the sound gets a bit muffled form time to time, but at the end of the day... its sonic.
Update: The Level select cheat code still works, well in a fashion. you have to tap the screen once then press:
Up,Down,Left,Right hold down A and press Start.
The level select screen will come up when you hit new game.
