Very glitchy and too easy

If you make another version of this, you need to fix some glitches:

1) you can continuously shoot one piece of coal and rack up your score, as it keeps on doing the exploding animation.

2) Sometimes It shows the game over screen, even though I was never touched by a piece of coal.

3) Not a glitch, but make it harder. I stopped playing as I could have gone on forever.

Good use of music (the muppets rock!) but next time, sort out the glitches and make it harder, and you could have a good game here.

You might wanna fix the glitches

Like the ones where you don't upgrade or how you can go off screen.

Sweet

Hey nice game but its a bit weird coz the game gets easier and not harder as you go along :P lol

Not bad...

I'd judt like to say that the music was annoying to me. As soon as it went from the harmony singing to the loud rock song, I turned off my speakers. The concept isn't bad, but you can't really call the new levels "upgrades," just "levels." Other than that, it was nice, and I like how moving forward makes you go faster instead of just moving forward.

Nice songs

It needs some work... 1) you can go woy off the screen. 2)NOTHING HAPPENS WHEN YOU WIN! besides that nice game:)
