It delivered what it promised

The actual game itself worked very well as a mouse skill test... I failed... but I was using my laptops li'l pad-thingy...

I think it could be alot better with some really small additions.
A particle engine would really make the game a bit more visually
exciting... probably just simple bitmap based particles so there
wouldn't be any real noticable slowdown... very easy to implement.

Maybe some variation on the movement... nothing crazy, just some
variation on angle and speed as the game progresses... they could
probably bounce off the wall if on an angle (like pong or arkanoid physics).

Well, there's my input, hope it's helpful.
Not complaints; just suggestions. It's a very solid game in a coding sense.

kinda...

good i admit it, simple most of it let me tell you
with more efects and something else would be better
more levels and more dificulty to find those skulls would be a lot better
keep it up you deserve this rate

Effort I see...

Well.... the ad with the nude people was.... Interesting and the game itself was very unoriginal!
shooting skullls!
I've never played such a fun! GAME!
Try and put the ad at the end of the game or something...
It was kinda annoying
