Back when Sonic Worlds engine was in the beta (or alpha?) and missed stuff such as goal posts, water, and bunch of pretty essential stuff like that, I tried to edit the engine to be more Sonic Advance oriented. This was prolly like 15 years ago lmao, I didn't get super close to proper Advance style but yeah, Sonic Worlds + Advance is something that's pretty uh, let's say close to my heart. This and Advance 2 engine are both amazing, not sure if I'll be doing much with them concidering I like to build my custom stuff nowadays, buuut having these around is real great!
