i dont think the progression is very satisfying since the difficulty is very static. like i think the appeal of incrementals is that you start off weak and then become super strong, but you don't really feel that here because the puzzles at the start are so easy, so you just feel "strong" the whole time.
i think it'd work better if you just started out on a big puzzle so that it was actually hard to connect pieces at the start, but then as you upgrade it becomes manageable so you really feel that progression.
