Cool idea. I think a couple minor changes would really help this stand out. The drill could be a little more responsive, so I could make minor adjustments and not rely on luck to line things up. Also the screen should scroll to the right more when I advance. But it's a pretty neat idea, I had fun.

Very cool, great idea, had fun.

Interesting idea. Needs lots more polish though. :)

It's an interesting concept, keep working on it. :)

Not bad!

A good concept, pretty innovative. If the drill's control was less clunky, and with a little bit of polish, I feel this could make a good app.

Neat idea. A bit too easy because I never had too actually drill around the stone bits.
Could be interesting with more challenging levels.

Interesting music!

Interesting mechanic, but too unresponsive and unforgiving

Nice game, I found the idea original, and the game challenging fun. I've seen you've checked my game. Thank for your comment, I updated the info to make it easier to play.

The "snake" drill is a cool idea. The executions need some refinement (better drill response to commands, sometimes you can get blocked by your previous attempts into an unwinnable position...)
