Most of the people would be killed by the bomb in this game. But here in KCA Rush you use the bombs mostly to get you a bit upper in the air and you can collect flying airships. The is always few of them and for each level there is a limit you must fill with them. It is true that the bombs slower you down, so sometimes when there is no need for flying, go faster and they explode after you leave the place. Typically for these games you must not get on your back or head , to not crash.
