Thanks for playing.
The moves - i'm rethinking if they are needed in game at all. Players often say that it is very hard to find the correct move and I'm starting to think the moves are just overcomplicate things, at least the way they are implemented now.
Yes, puzzles are procedurally generated. The hardest part is to take into a count human's cognitive abilities, otherwise the difficulty is skyrocketing.
For the handmade puzzles - you are right. I have a list of "rules" of how to solve a puzzle and now try to come up with a new set of boards/rules. Also I noticed these rules sometimes just emerge organically when I try to solve it.
Reveal all unflagged squares- exactly, very good point. This will be present in new update.
