Sonic Forces Re-imagined

Sonic Forces Re-imagined is a mod that tries to "remix" Forces by adding new paths, tougher object placement, and improvements to some of the original stages' flaws.
Currently, it's still far from completion, with about two-thirds of the main stages featuring object layout changes and a handful having full-on terrain additions/extensions as well. It'll eventually expand to include every non-boss stage in the game (yes, even Episode Shadow and the EX/Secret stages!), with at least ten levels receiving extensions.
