I wasn't expecting that this would be one of my favorite games of the jam, and I certainly wasn't expecting to get a story about belonging from it, but here we are. x)
It's really responsive and the puzzles are well made (couldn't get past level 15 though, I really didn't see how to progress). The idea of hexagons with no adjacent hexagons petrifying makes for a great mechanic to base the puzzles around. The undo button is also really appreciated. The menus are simple yet look really good, which is somewhat rare in game jams. The difficulty increases felt evenly spaced considering there are only 15 levels.
I had an issue though where exiting full screen mode in the web application would delete everything between the first and last characters in the "turns left" text so that it said something like "2 t". Not sure if that's the game or if it's just WebGL being moody.
Overall though, I'm really impressed and looking forward to any updates if you decide to continue with the game in the future! :)
