Thank god, I like T2K way more.
And so do I Seriously.
That being said, it's like Stevie Ray Vaughans version of Hendrix's Little Wing. Some may think it's better, but at the end of the day, it's still just a remake
If you play Space Giraffe like you played Tempest or Tempest 2000, then you won't get very far, you probably won't get any achievements in the game and will end up with a pitiful score similar to OXM Dan.
Play the tutorial, read the instructions on how to play, don't think of it as a 'Remake of Tempest', because there are too many differences between SG and Tempest.
