- Original Release: 2004
- Developer: Thirteen4
- Publisher: Sega
- Original Platform: Flash


A flash game that is serving as a demo for Sonic Mega Collection Plus. This demo is a flash port of Green Hill Zone from Act 1 from Sonic the Hedgehog, although it seems like an odd way to try and promote a collection of emulated games by making a really bad flash port.
This demo isn’t emulating Sonic the Hedgehog, it’s the first fully running in Flash, which means a lot of alterations. There are no slopes or loops, everything is a straight line. The screenshot above is what I’m pretty sure was a loop in the original game. It’s a really strange experience because of this, because the graphics look right, but the level design itself is off.
On top of that, the controls are wrong. There’s no physics or momentum, and Sonic’s jump is very stiff and feels completely wrong.
This is a really interesting game despite this, as it gives us a glimpse into what a flash version of Sonic 1 might have looked like.
