Descend, upgrade, descend further. Flat 2D suits it becuase your progress is right there on screen as depth. Nothing fancy about it. The classic played straight.
Dig down, grab what you can, come back up, spend it on better kit, go deeper. Thats a loop that has worked forever and works here too. Easy to leave running on a laptop.
dig down, get yourself in over your head, haul the load back up and buy whatever lets you go deeper next time. Ancient loop. Still does the business. The two things I need from one of these are a descent that feels costly and an upgrade that lands the moment you buy it, and this hits that often enough that I kept going back down.
