This game doesn't seem to have much of a purpose or goal. Controls are annoying (No repeat on keys? urgh.) and there's no risk to just mining the whole place out, and no reward for it.

This game isn't terribly interesting, its rather repetitive. Some form of death or time limit might make it more challenging.

I think some of my brain cells died... ok it wasn't that bad, but it was not really fun. I mined up until a score of 1000 just to make sure I was not missing anything. I enjoyed your intro, just would have liked a little creativity... boxes and miners... uh ok. Sound please! Decent submission mate.

Not bad but nothing special. Gets rather boring quickly. And frankly I also went to 1000 for the same reason ranklar did (before reading his comment). Go figure. Again, not bad though. Good luck.

Congrats on your first outing. :) I chuckled at the intro story. There is not much to do in the game since there's no danger or resource limitations or constraints; I just made an efficient pattern to cover the grid and picked up gems when I discovered them. 600 points before I gave up.

It's starting out promising but then doesn't really deliver.
You've got the basic mechanic down. Now you need some challenge. There is no way to die or to win. Also, having to repeatedly release/press keys is rather annoying.

It is good that you entered Ludum Dare and submitted something. The intro was intriguing, and I'm sure with more time the game would have lived up to it.
