I have noticed this too. I have been playing it quite a bit. There is no reason to have one unique solution per board though.
Some thoughts:
Insane is not harder than Hard. Often times the opposite seems true.
Scratch mode auto-committing on win is a bit too nice.
Dark mode is whack, terrible contrast.
I would like a player profile with stats and so on.
Random Insane seems to play like one of 50 levels. I recognize them often. Seems not so with hard. Now I just enter the puzzle IDs in turn...
Some puzzles seem to have no prior solutions as my time is often exactly the global average.
I would like to know how many solved a puzzle. Also if I did.
Overall great job and I love this. I would like it to be an app or something that can be bookmarked.
