Wow! That is actually very adictive for a simple idea. This has so much potential to be made into a great game with more depth. Add powerups, lives etc. I have one problem with the mouse movement. It's kind of jerky, I suspect this is because you are using something like:
xPos=xPos+mousemovex()/4
or something. If you are then that can be fixed by adding a .0 on the end of the 4, it just means it will come up with a decimal answer like 0.25, rather than rounding it to the nearest integer (0).
Great game, keep up the good work.
EDIT
Btw, my top score: 9800 and something
.
Do you bite your thumb at me sir?
