I've got all of the upgrades except collector ones, and I can't seem to make it to depth 10 to unlock diamonds. I've reset my runs a lot as well, trying to get good RNG.Am I missing something?
Tbh its possible that you could've gotten extremly unlucky with the ore spawns or the slammer movement, or both at the same time.
I'll try to keep playtesting over the weekend and see what I can do to make it better.
