The physics and the complexity of the city is pretty remarkable stuff. I personally struggled a lot with figuring out where to go. I know you mentioned there is a sequence to memorize, but for the life of me I just can't seem to navigate my way around the city properly. Most of that is just due to me as a player, but it would help if there were a few unique landmarks within the city.
It felt great to take off on a fully-charged nitro blast, and the UI for the nitro & map were both great. I may have struggled to get a grasp on this game, but I can easily recognize the skills you have, and the high level of execution on this game. Great work!
