It is a lovely little game. I think the first problem is in your marketing script. You call out negatives (doesn't have plot, soundtrack, etc) right away. I actually was expecting a silent game from this. Instead it does have sound effects, even if minimal. Regardless I don't think drawing attention to the negatives helps you. I also think the hole and wall graphics aren't helping sell it - they don't 'fit' all that well in my opinion.
Despite that I do think you prove the point that the previous poster requested. Unfortunately yours is one of many examples of well-done apps that doesn't get traction.
Do forgive the critique, I hope it will be helpful to you in going on to make ever more amazing apps. And I'll curtail my suggestions here. :)
No, they are very welcome. I learnt an awful lot about how to make a very good 'core' game engine, and how important everything else is (in some ways, unfortunately, more important).
One day I'll hopefully manage to make a new game, with both parts done well.
Algorithmically. The game actually came out of a research project into generating and automatically ranking the difficulty of puzzle games.
I have a long term plan to write a new game, with different puzzle games in it, using the same technique. The main slowness is a) Playing around with HTML5 and b) Figuring out how to make money off it (as with a webapp, you can actually lose a lot of money with hosting and servers, instead of the $100/year cap from Apple!)
