Hmmm... you added specifically - A storyline, for people who love stories..... A trial or so, puzzle like quest to collect coins, which was a lengthy part of the game, for those who take it slow, and enjoy it... And a fast paced race, for those who love a challenge, and want to move on to the next thing quickly.
Either I'm dumb, or I got that all put together, you tried to make a perfect game? Your games always end up being art lol... It's good because everybody gets what they want.
Anyones, regardless of my tired rambling- Loved how you experimented with the blur effect, added a little more to the game.. Black babies dreaming of the racing? *cough cough* Just kidding.... Good game, hopefully you make another great piece of interactive art like this again soon.
