It's a word thrown around and overused but Luxuria Superbia is actually a unique idea. It's a simple game that's as much about one's interpretation of it as it is the basic mechanics that propel it forwards. It's also going to make a few players blush a fair bit.
The reason? Luxuria Superbia is all about exploring a tunnel, while touching (or caressing if one prefers) a series of stylized flowers and other parts of the level - with the conclusion resulting in a sensual explosion of sorts. The connotations are pretty clear as to what's going on here, but Luxuria Superbia reinforces it with words of encouragement every now and then. It's also vital that one doesn't over caress otherwise the game is overwhelmed and players have to start the level again.
It's a very different experience from anything already out there. Some comparisons could be made to arty experiences such as Flower but Luxuria Superbia is still its own thing. There's more of a game element than one would expect given the 12 levels in which to explore, but explore is the correct word with stumbling around being the order of the day early on. Kind of like with people and the experience it's centered around, really.
