The game is fun, although it needs to have the gay tag added as 3/5 of the official levels (if you include the easter egg one from the demo) are gay content. Also an anal sex, oral sex, and titfuck tag would be nice.
However, there are a couple bigger issues other than the tags that are the main reason I've docked a star instead of giving it a five:
1. There's no proper gallery mode, instead you have to enter a cheat code that automatically plays the levels for you. So if you want to view a particular loop you'll have to enter that cheat, start the level, wait until the loop you want, and then you only get to watch it for as long as it lasts in the level.
2. The nature of the game requires that you pay close attention to the bottom of the screen where the notes scroll across. The problem with this is that it means there's no real way to view the animations while playing the game without either having amazing peripheral vision or taking very brief glances. So it's like playing a rhythm game while playing an HMV on the side that's synced up to the song in the rhythm game.
Essentially what I'm saying is that the porn and the game feel... disconnected. I can't really pay attention to both at once, nor do they feel like they have much impact on eachother.
