Pretty good. Not as infuriating/difficult as Getting Over It but I can definitely feel the inspiration from it that led to this. The difficulty is honestly just right in my opinion where it feels less like a rage game and more like a puzzle/platformer game, so I find it quite enjoyable. There is a huge difficulty spike at the second-to-last checkpoint that had me stuck for over two hours, but once past it the difficulty returns to normal. Overall a good time and fun challenge.
