Game-design wise, definitely one of my favorite games in this jam. A cool take on the role reversal concept. Also, my nickname is Ollie so that helped. I'm a big puzzle game fan, and I really liked the concept of one state pushing objects and the other pulling objects. Very cool idea.
The mechanic for swapping roles didn't feel very intuitive for me, so it took me a while to understand what was going on. The swap mechanic is also a very restrictive mechanic. That restriction, combined with all the fail-states that come with sokoban puzzles, made the game feel very unforgiving and fiddly. Puzzle games are great if you have an "aha moment" that lets you solve a puzzle, but I didn't have those here. All the fiddly details made it hard to form a plan, and instead I would just move everything around half-randomly until I found a solution. The difficulty ramps up very quickly. I think you could have included 2x or 3x as many easy puzzles to introduce ways of thinking about different problems.
Awesome game! Made me think harder than any other game in this jam so far.
