Here's something to keep you going for a little while, the Humble tinyBuild Bundle 2019 went live today and it has plenty of Linux games.
If you pick the lowest tier at $1 you will get:
- Punch Club
- The Final Station
- Diaries of a Spaceport Janitor (not on Linux - only one "Platinum" Steam Play rating, no others rated yet)
If you wish to dig a little deeper for more than the average payment, you will get access to:
- Hello Neighbor (not on Linux - "Platinum" Steam Play rating)
- Streets of Rogue (one of my favourites!)
- Party Hard + Party Hard: High Crimes DLC
Finally, for the top $13 tier you get:
- Party Hard 2 (not on Linux - "Silver" Steam Play rating)
- Graveyard Keeper
You have just under 14 days to decide if you want to pick up a copy. Check out the Humble tinyBuild Bundle 2019 here.
Actually not bad at all, worth it alone just for Streets of Rogue which costs quite a bit more than this bundle! The Final Station is also quite highly rated amongst users.
