What Can You Upgrade?
The site currently tracks Bag, Energy, Buzz and Speed. Exact live costs remain unknown here, because the August 21 update explicitly changed upgrade pricing after launch.
Bag
Bag upgrades should matter when your route is limited by carry capacity or repeated trips. Buy this early if you keep leaving useful trash or finds behind.
Energy
Energy upgrades should matter when longer cleanup sessions are limited by stamina or repeated action pacing. Prioritize it if you can find cards but lose efficiency before finishing an area.
Buzz
Buzz is tracked as a player stat, but the exact gameplay effect and cost need post-launch verification before this page gives hard advice.
Speed
Speed is useful when travel time between heaps, table, shop and grinder becomes the bottleneck. It is less urgent if your main blocker is card identification or repair.
Which Upgrade First?
A conservative first route is Bag or Energy, then Speed, then stat completion. This is guidance, not a verified optimal route, because exact prices changed after launch.
Upgrade Achievements
My Better Self! unlocks after buying an upgrade. I Have the Power! requires 20 upgrades. Champion requires one stat at MAX. Power Overwhelming requires all upgrades.
Known Reset Issue
The August 21 update says upgrade and money progress reset after the demo was planned because of in-game changes, while card collection was preserved. Treat current reset reports separately from that demo migration.
