@EspenLeeTennant, DragonArcherZ: I'm actually planning on making a sequel/remake that follows the popular Flash game concept play->upgrade->play->upgrade. This includes a complete redesign of the graphics as well, which means I will actually be able to put textures on the ores. Probably going to put in some sort of opposing force, too, to make it more challenging.
It was a bit of a risk to put a puzzle like this on Kongregate. I'm glad some people seem to be enjoying it, though I doubt the rating will stay so relatively high.
I can see how that would be a problem, Solitary, but none of the walls should be off-grid. Unless you mean the moving walls, but in that case I made a compromise. If I interpret your comment correctly, you think they walls should move in grid steps, slowly. I wanted it to be easier to tell when the block was about to hit you. If this is what you mean, I'll change it locally and see if I like the change, but clarification would be great anyway.
Thanks for the input... uh... buttluver.
The 1/2 space thing used to be a psychological red herring, but really I put it in for an earlier version. I see your point, and will probably remove it in an update.
And yes, the walls. I first made them instantly kill you because that's what the Towlr did, but with the moving blocks it's pointless.
Thanks for the input, it is very much appreciated.
