Wow.
as far as "first flash games" go. this is amazing for your first game. if this was just an ordinary game the rating would be a 3/5 but since its your first its a 4/5.
very nice ive always wanted to make a game where you go faster and faster youve inspired me. (i wanna make a game where you reach insane speeds and complete the game by reaching the speed of light) annyways. very very good only a few things. make it so you can reach insane speeds. players love that. also you might want to change the font it looked alittle eh... also. make the score unselectable. again. very nice i cant wait for your sequil. also for highscores. thats easy just use mochiads. you can also get money from the games you make! heres the link http://tinyurl.com/mochiads
