Rayforce is now out on the App store for iPhone and iPod users. It's the classic shoot 'em up you remember, but there are some new features like the obvious touch controls. Additionally, you can view the game in the original arcade aspect ration setting or play in the newly added full-screen zoomed mode. Plus there's the option between manual and automatic firing controls now.
The only downside is that Rayforce is going for $11.99. It's weird, that price would be normal if it was on XBLA or PSN. But on the iPhone? Perhaps I'm just spoiled by all the $0.99 games available on the App store.
