Really, really enjoyed this. The puzzles were a mix of "I know what to do, but I don't know WHY I know what to do" (which for my money is the mark of a perfect puzzle) and "aha" moments when I figured them out.
Never felt cheated or like the logic wasn't fair, which again is the gold standard for a puzzle game. Literally the only one I had any complaint about was the last one, because I was able to generate shapes that clearly looked like '2' but didn't register as the 'correct' 2.
I would absolutlely buy a full version of this!
