well something like slug% or also 100% (4package% + all slugs + spheres and sloops + all milestones + all harddrives) would be possible. after you stopped the timer you have to show the amount of these items you have. but therefor you need to know the exact amount of all of them and espacially slugs could be tricky cause you can get them by doggos. on another board we add new categories if there are people running it. if something works and also makes fun (or not) is difficult to say without having tried it in a run.

What about a short guide of the setup? Which files can be deleted? Would it make much easier to get into the run. :)
