i kinda couldnt find the exit, fell out the map trying to dig myself through. Pretty nice overall, cheers

The base idea is good, but something else also needs to motivate the player other than score.

Either it be destruction being satisfying or some type of progression.

In short good idea, could do with some more polish / features.

++A volume bar is almost a must in any game I feel, nearly blew my ears the moment the music began. 

I found this game to be very one-note. Once I realized that none of the tiles meant anything and it was just a score-chaser, I didn't see much motivation to try and get as many as possible.

That said, I still think there are lots of things you could do to improve this:

• Considering there are different types of tiles already, I think each tile should do a different thing in order to encourage decision-based play. Perhaps they could give a spendable resource? Just throwing out ideas.
• The camera is way too far zoomed-in in order to feel a sense of progress. As I approached the bottom of the world I wished to see all the tiles I'd dug out so far, but couldn't. I think if the player could see twice or thrice as much space it would be a big improvement.
• Please choose better music... I'm sorry but after the second loop that song began to really annoy me. I opted to mute my computer just to avoid it.

Thanks for creating!
