This is a proof-of-concept port of Sonic 1, 2 and 3 created in 2010 by Simon Thomley. It is improved based on the Sonic 1 port on the Game Boy Advance.
The project included several enhancements including playable Tails, Knuckles, and elemental shields, as well as a new Special Stage mode.

Gameplay

- Touch the screen to place the selected object at that location in the stage.
- Green Sphere - This sphere effectively takes two hits. One hit will turn it into a normal blue sphere, that must be hit again to turn it red. Green spheres will not turn into rings when surrounded by red spheres
- Purple Sphere - Touching this sphere will teleport you to another purple sphere placed somewhere in the level at random. There will be a brief pause after teleport to allow you to get your bearings
