I just appreciate what we got.
Including this?
It looks like Green Flower zone from SRB2 back there...
It is, but that's only for testing purpose since he's focusing at the characters first right now...
From the creator's Twitter :
"Disclaimer:
This is not SRB2. This is a fan project being made in Unity.
I've simply ported Greenflower Zone 1 & 2 from SRB2 for testing purposes until I'm ready to show off one of the actual stages."
