Ended with a score of 561, game concept is simple. Simple enough that you can easily add so much more to it. Things such as different kind of ores that does different things, like slow down time or make your mining faster. The one tip I can give you is to perhaps improve the music. This was my problem as well with my game, I couldn't get the music right so I didn't use anything. In you case, it's a bit short, so the music restarts quite often due to the fact that the game can last a few minutes.
Great job nonetheless!

I like the mechanics. The fact that moving in the air is cheaper than breaking walls makes you think the best path to get a lot of minerals. But it is very unbalanced, so after 10 seconds or so I stopped caring about making the shortest path because I had too much power. I guess tweaking a couple variables you could balance it more. I really see some potential in the idea, I think it can be improved a little adding more stuff like different minerals so the player has to think hard to guess which mineral should he go for first. Even powerups.
