Clever twist on an old mechanic. I like the way thr rules are constantly shifting too. And it got lovely presentation, and good controls, however...
It's waaay too hard for me! I always say that if you're making a puzzle game where the puzzles fun comes from figuring out a solution, once you've worked out that solution it should be pretty easy to perform it. Even having watched the walkthrough I think I'd never be able to perform most of the solutions!
I really loved Getting Over It with Bennet Foddy (clearly what this game's namesake is). That was hard, but not in a puzzley way. It was just a skill you had to build up through practice and repetetion. I got over it with Bennet Foddy, but I don't think I'll ever get over it with myself!
