I absolutely loved this game and it's one of the few games on Newgrounds that makes me want to play it over and over for more than a week. The idea and gameplay and everything about this game (as far as I know) is very original and very good. My only very small little thing about this game is that sometimes, even when you have a lot of enemies bought, there are about 5-8 seconds that there aren't any enemies which may be a short time but it costs a lot of fuel. Either way, this is a very great game. Keep up the good work.
