If you haven’t had a chance to read our review for Botanicula yet, the latest game from Machinarium developers Amanita Design, you should. The game launched today, and earned a much-deserved perfect score right here on Gamezebo. And it’s launching at the perfect price: whatever you want to pay.

Teaming up with the folks at Humble Indie Bundle, you can now snag the The Humble Botanicula Debut and name your own price, getting Botanicula, Machinarium, and Samorost 2 in the process (not to mention soundtracks for all three games). And if you pay more than the average, you’ll also get the game Windosill and the feature-length Czech film Kooky, which Amanita Design’s Jakub Dvorsk√Ĺ served as art director on.

So why the generous debut? Amanita Design loves the environment. As if the setting and theme of Botanicula weren’t enough to convince you of that, they’ve selected World Land Trust as the charitable recipient of your gracious purchase – and it’s up to you to decide how much of your purchase will go to the Trust, the developers, or the Humble Indie team.

So what are you waiting for? Five star game debuts don’t get bundled into amazing offers like this very often. Help save the rainforest, and get a slew of great games in the process.
