Fun little game. It reminds me of Kaboom! on the Atari 2600!
I died way to many times by the bombs. Although I didn't mind too much because his little scream is funny :) Nice music too. I also like how you get a random background each time you start the game.
The addition of power ups is great, and I think you should add more of them. What does the x2 power up do?
Cheers
