I don't know who you are or whether this is your first time using Flash… or indeed, using the Internet. If you speak English at all (second language??) I hope you can understand what I'm saying. Your game is bad, and can't be played. It is literally unplayable!
First, you can only go down or left/right, never up where the supposed "coins" are (they're just floating number amounts). Second, the game ends in about 3 seconds! Third, the music loop is only about two seconds long and very irritating. Third, the replay button doesn't work! Fourth, the icon isn't from this game and might even be stolen.
I don't think you can make this game better. I suggest you scrap it and try again. Take as many classes and courses on Adobe Flash as you can. Otherwise, your next game will also turn out like this.
