Looks like the line-up for the monthly Humble Choice for August is actually pretty good, with a bunch of quality indie games included so it's not one to miss.
This is the bundle that replaced Humble Monthly, where you pay for whatever tier you feel is the best value to get access to the Humble Trove (a ton of DRM-free games), a discount at the Humble Store and the ability to claim Steam keys for multiple top titles.
August has these included:
- ENCODYA - Linux native (GOG key)
- Superliminal - Linux native
- We Need To Go Deeper - Linux native
- As Far As The Eye - Linux native
- Out of Space - Linux Native
- Nowhere Prophet - Linux native
- Bloodstained: Ritual of the Night - playable with Proton
- Blue Fire - playable with Proton
- Carto - playable with Proton, use Proton GE to have the videos work
- Cepheus Protocol - might work with Proton
- Drake Hollow - playable with Proton
- Last Oasis - not currently playable on Linux, uses anti-cheat
