Liked this one! I had some resolution issues that I worked around by increasing the game window size in browser, but was able to play after that. I liked the timing minigame with the drill, and rescuing miners was a simple and fun premise. I think the timing is a bit strict; maybe the two holes that have to overlap could be bigger or move slower to make it easier to time. I got up to needing to rescue 5 miners before I missed too many overlaps and ran out of fuel.
Overall, this was a solid entry. Great job on the submission!
