Amanita Design [Official Site], developer of beautiful games like Machinarium and Botanicula is another well known name to put their games up on the itch store.
They now have these titles on there which support Linux:
- Botanicula Soundtrack + Art Book
- Machinarium Soundtrack + Art Book
- Samorost 2
You can find their itch.io store page here, with links to their games. They're all on sale too, a perfect time to grab them if they still haven't picked up a copy.
As a big fan of itch.io, I'm really happy to see more well known developers put their games on it. Their store is slick and easy to use, but the icing on the cake is their speedy open source game client.
