Hi! Glad you like it! If I can give a tip : The moles are really deadly if you get yourself in a corner; try using their tunnels and the naturally generating caves so that you have room to back up and use clocks and/or dynamite to distract it or kill them.
Also when try digging using the dynamites, past a certain depth they collect more than their cost in gold and create large openings that give you a little more room to escape the moles.

I know right?! They weren't scary until we turned off dev tools
