A peculiar and amusing approach to the Twiny Jam constraints.
The game has a relatively substantial story set in a vivid futuristic world - but tries to tell it in as few words as possible. Believe it or not, it has 11 different endings (see: time cave structure).
Like all games by this author, it's well-planned and well-written - but, first and foremost, it's just fun. You always wanted to be a member of a jetbike gang, didn't you?
Worth the (extremely short) time it takes to play it.
