This is a pretty good Cookie Clicker style game, but with a few issues:
1. You can very easily screw yourself over by buying too many early mines. I got 7 of the back-door piles and subsequently barely saw the higher tiers until I bought several of them, constantly being set back by the belt capacity. I can only see this problem getting worse as you unlock higher tiers.
2. The mines don't scale well. I stopped after buying one Geode Stand, which set me back $10k and even if that was the only mine I had, I still wouldn't be seeing that amount of money again for a long time. (Why is there still 25+% chance for a rock to have $0 at this stage?)
3. The upgrade info isn't on the upgrade itself, it's tucked away in a menu, which is frustrating, and some of them *still* don't actually tell you what levelling them up does. (e.g. Auto-Crusher)
4. Too much clicking at the start, my hand was starting to cramp by the time I got my first $1k for semi-automation. Obviously I could've used an auto-clicker, but that's not how you should be balancing a game.
5. Some of the upgrade descriptions are lies. The Collector still has 1 capacity by level 3, not 2.5 + 1.5x level.
Overall, this feels like a very old incremental. We've largely outgrown Cookie Clicker-likes (on web, at least) but if you wanted to get that experience across for the jam, I would've made the game *much* quicker to get through (like 10 minutes for your first ascension).
