Andtha: The only real critique I have about the new Humble Windows app is the fact that I cannot get the trove games and the subscriber exclusives as standalone installers anymore... I have to use the app now. But how to I preserve the exclusives for future use then?
The vast majority of Humble installers were (and should still be) just zipped installations. You can just install the Vault games, zip them and take them with you wherever you want. The Collective games, on the other hand (Dodgeball Academia, Forager, Unsighted, Void Bastards, Wizard of Legend) seem to require the app in order to launch, so you won't have any luck there.
