Point of fact, it gave me the "20 or more worms" achievement and I just won it after having gotten 19 out of 30. Looks like an off by 1 error. At least.
Why the hell did the mole SET OFF the explosion? Stupid mole. You should make it more obvious at first that it is not an objective at all to avoid the dynamite. I thought at first that the explosions themselves would kill the mole.
For some reason I'm reminded of the mole final boss in the no time to explain game full release. Even though it wasn't a cyborg. I don't think. Must be because of the lava. What kind of a mole is digging around on the edge of the Earth's mantle? Some kind of supermole? That isn't hurt by being right next to exploding dynamite? No doubt.
I like how you respond to every comment. I wonder what you'll do when you get to my usual deluge of trite drivel. Let's find out (submit)!
