I spent a very long amount of time trying to clear the full board until I finally did it with like 57 levels of the first and third powerup. Very satisfying and extremely addictive game, I enjoyed it. It looks great, and it made me really want to see how much I could mine. The only thing is that there isn't much risk. Maybe there could be bombs that look like biscuits and you aren't allowed to touch them, or something like that. Regardless, it was very enjoyable, great job!
