It's an ok prototype it does what is expected from one, but there's really not much to it, bare bones where what one of the car have all others are purely copy paste.

5 lanes are used while 9 others arent, since the 4 cars after the first are just copies, couldve at least made 9 more or not made that many lanes in the game.

glitch double points gained but after 4 levels on it, it escale far too much considering you wont get that many points much faster than before. If only instead of just doubling the points it also doubled the distance necessary for one lane, that way coupled with a better pricing for the other upgrades it could maybe make it a little more fun.

Overall the escalation in price/what a upgrade provide is quite bad, after speed/accel 20 and grip/nitro 10 u wont really get much from going further.
