I was just thinking about this game today and how I couldn't think of another game quite like it. Sure, there are plenty of other adventure games with a focus on pre-rendered art assets, but the level of detail and interactivity in Revelation are amazing. Tapping objects and the subsequent audio feedback incorporates the player into the world amazingly well.
 
What other games are this tactile? 
 
I doubt anyone will grace this particular forum for some time, so I'll save it as a favorite. Don't let the age of the post discourage a response.
