Victory comes at a really high cost! I love the simple graphics, it works really well. I have a single complain, when choosing a memory to sacrifice, I often advanced the text too fast and pressed "yes" without meaning too. For instance, I sacrificed a memory worth 7 points for a 3 points fight. It happened to me a lot.
I love how the controls are seamlessly explained at the beginning of the game, that's a very nice touch. Great job!
