I love the idea, VR should be a great medium for new kinds of multiplayer games and a combination of minigames in the style of Mario Party should be a great way to show that. Especially since it achieves multiplayer while only requiring one Oculus Rift. I can imagine a lot of people wanting to show off their new VR headset with a game like this, so I gave it a thumbs up on Greenlight for you.
One thing though. The character art style doesn't sell me on it as much as the gameplay. They look off-putting, and I wouldn't particularly enjoy having myself represented in game by a perpetually frowning character with a head that's half his total height, for instance. It doesn't make sense to play a fun, engaging game with weird, fat, scowling monstrosities.
Oh, and in the video your text is constantly flickering between yellow and orange. It looks unintentional and could cause seizures.
