It's SAGE, so here's Sonic Worlds Delta 1.5.2, the Sonic game development kit for Multimedia Fusion 2 and Clickteam Fusion 2.5! This version has been in development for a few months since BlazeHedgehog revised Shadow in 1.5.1, adding some very nice accuracy improvements and some bonus toys. This one is largely Ikey Ilex, so give 'im a round of applause!

Ikey sat down with the disassemblies on Sonic Retro's GitHub organization and refined the hell out of the engine. He also made things more efficient! The end result is a more accurate engine that uses less CPU.
Also, Ballhog was promoted from sample enemy reference to a fully functional recreation of the Scrap Brain Zone enemy. And those fans from Star Light Zone were added as well!
In case you missed 1.5.1, Shadow was dramatically overhauled by BlazeHedgehog. Give 'im another round of applause!
All other relevant information can be found in the included documentation, and the original OP of this thread.
Enjoy, and Merry SAGEmas!
