LOL That got really dark, really quickly.

Disturbing lol

I lol'd hard.

Fun and addictive, and not overly hard. And just my two cents, the turning is realistic. If you're boring through rock you don't make smooth turns like if you're driving.

Simple, addictive, and just wrong lol

This one's a classic. Just as addictive as the first, but more playable. I love how there's not a shot limit in this one.

Blinding light.

I love the line work. It's high contrast without losing realism. That's harder to do than most people give it credit for.

Beautiful.
