I've had VVVVVV for a long time, and I pirated it before that. But I've never stuck it out and beaten it until today. I'm actually quite surprised at how short it is - although there are other modes to try out and all the trinkets to find.
My favourite bit about the game is the music, truth be told. It's classic 8-bit music, except it's more detailed and the tunes are addictive. I could listen to it for a long time.
Least favourite bit is how finicky the controls are. Several times I overshot even though I was pressing the button the same amount as successful attempts (at least that's how it felt to me).
I like it, anyway. Not the 'omg amazing groundbreaking awesome' game I kept hearing it was though. 4/5 stars.
