I'm kind of surprised to find myself enjoying this because I've had a certain hatred for box pushing games. (maybe it's trauma from the sliding blocks in Pokemon games, heh). I guess I'm getting over it (maybe it's happy memories from Baba Is You).

Anyway, one thing that's fun here is that you can trigger the AI solve from any board state. So in particular on puzzle 12 I was interested to see that an initial push (to escape from the 'box' where you start) I'd written off as untenable turns out to be the optimal solution. Then of course it's fun to watch the solver tackle the initial conditions I solved under (and still beat my number of moves).

Might be kind of fun to play with "pessimizing" the puzzle - like, how can you move blocks around to provide a maximally adversarial place to hit the "solve with AI" button? (obviously you don't get to count your initial moves around the board, or you could just move back and forth to get the most pessimum (thanks, Mel) solution.)

Edit: Puzzle 14 feels odd. Super easy, why is it at 14? Maybe something tricky about it that I'm not seeing, perhaps the shape of the arena makes A* harder or something?

Also, 15 is interesting and highlights a theme I'd noticed, which is that often the initial moves of a puzzle seem pretty locked in, and the place where the AI shaves moves off my solution in in some clever approach to the "stacking" of boxes onto the goals. I guess that seems kind of obvious when I write it out.

Anyway, thanks for something to noodle on this morning!
