Ok I get it now, it’s making me do some stuff with the environment–jump up on this thing to shoot that thing, to make the block fall, so I can jump on it to be one level higher to shoot that other thing, to make a hole to get to the passages over there. I can do that. I’d rather not have to go back and forth with stuff I’ve mined to buy upgrades, but ok, it’s a mining game, I can dig it.
