Let me add this up...

Base of 5, just because I can.
+2 for smooth control.
+2 for great animation and design
-1 because there are no sounds
-2 because it gets boring FAST
So that's a total of 6 over all.

There are a few things which need fixing:
The menu needs to be larger.
When you star the game it lists the caterpillars as giving you points, not taking them away.
There really needs to be sound.

A story would be nice too. You could break it up into levels, change the sprites for a different feel each time, and add a score target.

Other than that, good work.

good, but two mistakes.

I think it's a really good game, but on the tutorial it says about the worms that they give points, but they only subtract points. Apart from that, it's a really good game. And by the way, I scored around 3600 points, but the highscores don't work for me.

Meh

A couple of problems:
1.) The high score system is broken
2.) Umm...
3.) Imma continue so that my list format isn't unnecessary

buggy

my score is always 0000000 at the end. And in the help screen is shown that worms gives points, but in the game you lose points!
