"We've had Sonic The Hedgehog 2 Dash!, now it's the turn of Crash! And if that sounds confusing, well, it's not. Basically Dash! was the first half of the classic game Sonic 2 for mobile, and Crash! consists of the second half, from the Mystic Cave to the game's final bosses.
If you're wondering why the game has to be split into two, you won't be wondering once you've actually played it.
This is Sonic 2 in all it's glory - with ten multi-layered levels packed with enemies, platforms and pretty backgrounds and its main mammal character (and sidekick Tails) whizzing about the place like a hurricane with blue fur."
