Interesting game. The drill feels overpowered given it seems far more efficient to outfit a single dwarf with one than bother with a whole team, let them clear the level then use it to dig down. At a certain point Iron stops appearing and the drills get too costly to keep going. Would be nice if other resources could be used.
I agree that the camera is painfully slow and I would greatly appreciate being able to scroll with WASD/arrow keys not the mouse. There was also a bit of frustration around trying to lay down paths vs. getting a dwarf to just move to an area and selecting/unselecting them when they are moving around fast. Some kind of key for deselect or even drag-box to select multiple at once would have been great.
Enjoyed it, though I don't think there's anything that compels me to want to play again. I got to level 10. Thanks for sharing!
