Sonic Regress - Robotnik's Rampage (Demo 1)

Sonic Regress is a fangame trying to follow the functionality of the classics of the 16-bit era (powered by GMate Engine), with the goal of being another classic Sonic adventure.

Story:
Another of Robotnik's plans has been prevented by the blue hero and his friends. Although they have restored peace, the evil Doctor is far from giving up... looking at the Master Emerald data he collected before losing it, he twirled his moustache as he thought up another brilliant plan... using the data, he realized he could try creating a Chaos Emerald prototype... to make sure his plans don't fall easily, he created two.
Being Master Emerald's data used, the prototype acts like a Chaos Emerald, making his machines more threatening.
Sonic and Tails with nothing to do, went for a ride on the Tornado, and they realize something familiar on an island, Death Egg under construction... both went to the island, but one of Robotnik's machines hit the Tornado and fell into the island, near a coast. It's now where a new adventure begins.
(Knuckles will not make an appearance, he has no reason to get involved in game's story, he's on Angel Island.)

SAGE 2018 Demo 1:
This demo was a bit rushed, only 1 zone is playable: Sunlit Viridi Zone (Viridi is Green in Latin)
Boss haven't been added yet. Was thought to have this Demo, but as nothing seems easy and as this Demo was rushed, you at least play both acts.
Demo 1 Tails' sprites weren't made (actually yes, but I rejected the new sprite), but his palette is here.
Most of the Demo 1 musics are placeholders, only 2 were made.

The project doesn't promise, it just does the best it can.​

In the next demo, you can play Extra Zones that aren't part of Regress but of others.
I don't intend to reveal one of the extra zones, I just say they will have 2 acts, the 1st for Sonic and the 2nd for Tails.
