I have a lot of fond memories of play testing Daniels games in his office. This feels like one of those games. Its a ton of fun and the mechanics are straight forward enough that the player can get an intuitive reaction to the visual prompts.

Wow, this game looks fascinating. It reminds me of a game from the mid-90's, Rocket Jockey, with its competitive and combative racing and the ability to attach to other players, with visuals that recall the Tron movie of the 80's and other sorts of landscapes that one used to see in 80's media. It is so awesome to get to see what Daniel was working on; the visuals and the gameplay both seem very compelling and look as though they really compliment each other.
