In Brain Cars, you have to drawing a line that your car will then be travelling on. It’s continuously moving forwards, so you’ll need to quickly react to many different obstacles. Try to make the road as straight as possible, since the car can get stuck and you’ll have to repeat the level. Aside from that, you need to collect fuel, since the car will be burning through it quite quickly. The collected coins can be used in the store to buy new cars or unlock other game zones. Have fun!
