I just bought...

[hmpf]

... Blueberry Garden, Sword & Sworcery, Botanicula, Machinarium, Samorost 2 and Windosill. (The last three links lead to playable online demos. Here's a pay what you want bundle of Botanicula, Machinarium, Samorost 2, Windosill & an animated movie.)

I just may die of an overdose of beauty if I play all these in the next few days.
