Use A to move left and use D to go right. The bombs will fall from the sky in random places and if you hit one you lose. If you lose just hit the green flag to play again. If you get the chest you will gain 100 points and move up 1 level and coins are worth 10 points. The bombs fall faster as the levels progress, so watch out!
Thanks to Smiley5 for the original game, I just made the bombs fall faster as the levels progress. I also added coins, but so did smiley.
