So, there was no news again for a long time. But here I am, come to say that Knuckles, and his first Solo path will be here in the coming months.
In the meantime, here's a list of innovations:

Added levels, new types of settings and features.

The graphic part has been completely updated and can be adjusted in the settings.

The dialogs have been updated, and my previous translator did not perform his direct duties, so I translate everything myself. I am looking at you, Fellon!!

New game mechanics for Knuckles have been introduced.

The Chaos design was slightly changed.

I also updated the graphic component of the game jolt page, but it's just a small thing.

It seems to be all changes. Good luck waiting for the new demo of Sonic.exe the stone of darkness!
