The mobile puzzle-adventure game The Cave is free right now for Android devices on the Amazon Appstore. The usual $5 game just hit the Amazon marketplace a week ago.
It's strange that The Cave is being offered free especially when just being released but free is free! It's possible this is a mess up or someone just forgot to announce this great deal. Not feeling The Cave? Grab Cogs for free now at Amazon as well.
Developer Double Fine's little platformer is also available on other platforms including Xbox Live Arcade with excellent writing, engaging gameplay and creative art. It's not going to blow your socks off but it's one of the best mobile games of its kind. Read our review here. Check out the announcement trailer above.
