It is honestly impressive how bad the platforming is in this game. Like they even screw up the basics like "don't introduce 2 mechanics at the same time". Like the double jump crystals seem to only work with perfect presses, so they add fading platforms on top of trying to learn that timing? Then jumping immediately to advanced forms of said puzzles (strings of double jumps followed by strings of fading platforms) immediately after dumping the mechanic on you? Mixed with the lack of checkpoints meaning you have to do the entire screen over again makes me wonder if the dev even actually plays the levels or just cheats through them.
