qol, its really hard to sell items from your stash unless your inventory is empty.
but with mining for upgrades, you've set it up so that the high-end titan's strength can possibly rule the leaderboard? and by having that be so expensive -- i've barely managed to reach 1000 stardust with an autoclicker's help -- you're making the board about pain and clicking, not about 'builds' .. at least unless you add 'leagues' based the level in titan's strength, but that may be silly.
tldr; qol's mostly fine, but the constellation upgrades seem to be priced way to high (for someone who does not want to be married to the game)
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.
