Hi just stopping by to say what a GREAT witness-like game! I've tried a lot of puzzles here and don't usually comment to congratulate. I have to say this is among the best in terms of deducing the rules. Congratulations! Hope you keep developing more gems like this!

there should be a way to save progress.

One of the best puzzlers I've tried! Congratulations! Now you need to continue development and make  new levels!
