I pushed last night a auto sell function in profile> settings. This should help with the selling so that its down to not as many items. There is a sell all button in inventory if you have at least one item, and I added some item tabs to try and narrow it down more too, let me know if you have any idea. Yes the mini game is very new and Im also not super in love with it, I was just trying to add more depth to mining, and also try to give some depth to seasons when I start that, where on first week you get 80% of your upgrades first couple days which will be enough for most to feel "completed" until next season, but leave some meat on the bones for people who still wish to get more out of the game once 99. Open to ideas though on this or anything really, just trying new things and seeing how they feel or stick. Also pushing alot of speed calc updates and logic this week to help with leaderboard people owning it with speed builds.
