Sonic P-06 general

Can someone tell me why character jitter like that when he's falling at 1:50? I'm curious because I also noticed this effect in ShTH and Forces.

 

That appears to be the camera struggling to rotate properly in the air.

 

I know how it feels to have a small fix snowball into something bigger, ha.

 

I haven't been following this project very closely but I am interested in checking it out. Does Silver release contain Sonic and Shadow campaigns or do I have to download each release separately?

 

It has everything. Each release replaces the previous one.

 

A preview of End of the World. Shows off a lot of visual and gameplay improvements.
