the numbers get pretty hard to read on a switch lite at larger puzzle sizes - in particular, once a color chunk is detected as 'complete' (and it becomes a number written in that color on a white background) it can be very difficult to discern what color it was, and i suspect this'd be a problem even on a larger screen. also like two or three of the 35x25 puzzles at the end were bugged and not correctly detecting completed sections in certain rows (can still be finished, just annoying)

there's a charmingly amateurish or perhaps 'programmer art' quality to a lot of the finished pieces that i really enjoy though – they're not badly done, there's just a certain goofy looseness to the style that i find charming
