While still being a WIP (disclaimer: expect some changes); it's now advanced enough to provide a preview.
The gameplay is inspired (not a copy!) from the Special Stage as found in Sonic the Hedgehog 2 on the Sega Megadrive. Of course, it has been adapted to match the Amstrad GX-4000 limitations.
Gameplay description: with the Special Stage, Sonic can't lose anything, only wins an extra new life. He must collect rings on time, while avoiding holes and bombs.
We are still working hard on Sonic GX. For sure, it's taking more time than expected, but there is no need to rush its development :).
