Welcome to releases! It's a fine port of the old Adventure features, even giving Amy a hammer jump reminiscent of SA1!, But I really hope there's an update to disable the camera changes. I swear there used to be one back in the day (unless I missed if this mod has it?), because man... That's the one element of adventure mode I really didn't want to come back! Still, this mod makes for a good resource, as well as something to mess with!
It would be pretty cool to have a mod akin to SA-SRB2, but I doubt anyone would be willing to take the time to revamp the entirety of the main v2.2 campaign to accommodate for Adventure Mode.
