Yes... this is a mod of the engine. this is incomplete. loops are kinda sorta very partially buggy i had to do some trig for the ring circle placements there is a bug or something like it in Scratch that causes the turning and location for Sonic to look good. If you want some story Sonic's world is starting to become less pixelated, starting slowly with some entities of the level, and even entire level parts are becoming vectorized. Who knows where this could lead.
Credit to Tomicool for the original engine, the reason it doesn't show is because I uploaded the mod in a new project. Credit to Sega for all the art and move set from Sonic Frontiers. Basics arrow to move x to jump down + x = spin dash x in midair = double jump, then drop dash c + x = drop dash z = boost z midair = air boost c + down = stomp x + up = peelout x + up midair = air peelout once the up key is let go x + down + c = instant spin dash on the ground x + stomp land = stomp roll l = swap from Lost World and Default jump and double jump Advanced stomp roll + instant spin dash = stomp dash
