Spirits for iPad, which I saw and played back at Indiecade this year, is out now on the App Store. The game is US$4.99, but as a premium iPad experience, it's worth it. The whole thing is extremely relaxing, and the art style is quite well done. If you enjoy Lemmings-style puzzle gameplay where your goal is to get a set of autonomous creatures to a level exit using their various abilities, you'll really enjoy finding your way through the 40 handmade levels in Spirits.
I was told a while back that an iPhone version is coming, but the iPad version was ready to go first, so here it is. Unfortunately, there's still no Game Center achievements or any other extra modes or gameplay, but that's ok. The point of the game is just to sit back and explore the world with these weird spirit creatures, so if you're looking to spend some quality gaming time with the iPad this weekend, Spirits won't let you down.
