My submission for GSE-Fest 8. A short demo, to say the least. I liked how it turned out. I don't really work with GSE because of the wonky collision, but it's fine.
I made some custom sprites (Based off of Sonic 3). Object and camera system made by me. Thumbnail artwork made by me. Thanks to @hahasamian and @tomicool for the original engine. C2A (Credits to all)
