Good game, but could be better

I like this game a lot. Some ideas after the upgrade:
1 - The nitro is a good idea but recharge it with near misses isnt so cool, recharge with time, thats a lot crashes at that speed;
2- the arena mode is very nice but we could choose use the nitro or not at the races;
3- at arena mode, instead the oponent be a ghost car, make it real with the chance of bump each other and crash with the rest cars;
4- put more cars and drive at night with the headlights on.

Thank you for listening
