One of the things I wish I had time to implement but had to end up scrapping were little cutscenes between the race and blade phases where the enemy would appear and the player's car would transform into the blade, just to give it that extra bit of narrative connectivity. Like the player's car slamming on the brakes and drifting off-road into the arena to fight Grey Blade, or Titan Blade dropping out of the sky like a meteor and blowing a crater in the middle of the road.
