We've been doing a week of experimental indie games in this space, and here comes Strange Rain today, from the creator of previous iOS indie title Ruben & Lullaby. Like the other games featured, Strange Rain is really more of an experimental art piece than an actual game. Rain falls on your iDevice's screen as the app plays, and it's really just an opportunity to sit, relax and experience things as they happen. There are some extras and secrets to go through -- a mode called Whispers Mode adds some words to the mix, and a Story Mode actually tells a story as you interact with the screen.
What's fascinating about the app is that while it starts out as a rain simulation, following through with the experience turns things a bit, well...strange, and it's up to you, the player, to discover and find what meaning you want. Like the other experimental games, this means that the experience is a little more open-ended than just earning points (though there is Game Center integration in this one -- that's a fun bit). It's up to you to figure out how you'll react to a "game" like this, and for some players, that can end up being very fun as well. Strange Rain is US$1.99 for the universal version on the App Store.
