Technically it works but the level design is bad compared to actual Sokoban. It doesn't gave enough constraints.
Yes, it's after multiple attempts at the problem. It's hard to nudge it to have it come up with an algorithm that generates 'interestingly difficult' levels.
I'm sorry, but it looks like someone's tiny game demo when they're learning HTML, with random mismatching assets pulled from some free packs (I guess in this case they're just generated). I fail to see any novelty or technical curiosity in this.
Please share more what you would expect out of sokoban as an AI coding benchmark?
Hey an ad-free sokoban. Looks better than most. Nice.
