Your game has a bug which is relatively common in drag-and-drop games. If the viewport is smaller and I drag a match off-screen by accident, it can get stuck to the edge. Then it can become detached in such a way that makes it impossible to recover the match.
I created this game because of an old news my wife shared with me, it was about The New York Times bought the Wordle game. I was then surprised that such a simple, old-style game caught the attention of a big company. I said "I'd rather play a matchstick puzzle", and it was that moment that inspired me to create a free online version with all the puzzles procedurally generated by my own hand-made solver (I like the sound of this :D). Personally, I like moving one and only one matchstick to solve a puzzle rather than 2 or 3 sticks, also I don't like those tricky solutions like negative number, rotation trick and etc. although they could be a very creative solution and let you think outside the box sometimes, IMO, it is just not elegant and sometime distracting to encourage people to think in a systematic way.
I remember one of my freshman computer science assignments was to make a Rubik’s Cube game. That was when a lot of undergrads were first introduced to the idea of using a stack and then "unwinding" it to simultaneously build the problem + solution.
Just like "hand-made" pizza used as a response to the rise of frozen, factory-produced pizza and to establish authenticity against fast-food chains. Maybe "hand-made" will be used to emphasize a app/software is made by human rather than being vibecoded or completely AI generated in the future. Also, if you use the Puzzle Maker to create your own puzzle, it becomes a "hand-made" puzzle :)
