A bit of both, made a generator that spits out games and then I played 10 procedurally generated levels and picked the ones I liked.
In general my favorite levels are the 7x7 with 5 stones, you can legit logic them out if you are patient. I only put in one since it takes quite a bit of practice to get to that point.
You should be smiling - this is really a decent puzzle game. And the last level did take a couple tries before I got it, but that was great. The earlier levels were too quick and easy once you figured out a couple patterns to look for.
Everyone is correct that this needs a better intro and better overall UX. But the concept is solid enough that I think this idea could go somewhere. Well done.
