*it's INSANE* the amount of work put into each separate part of his body for the animations!! just an all around stellar work for the team behind this mod in general!
I mean it was made in late 1990's so I understand why it has so many mods. Still though I'm insanely impressed with what's on display here, like they straight up recreated all of his gameplay from adventure it's insane.
It's multiple sprites with their position moved smoothly to give the illusion of a 3D model. If you look closely at each individual "piece", you'll notice that they still only face 16 directions.
As much as I do admire how incredibly detailed this mod is, I don’t think it’s for me. Gamma doesn’t really seem designed for the Simple control scheme, which is how I prefer to play SRB2.
