Great game.
I had alot of fun playing it, especially after the bugs were fixed. Originally the game got too tedious, mainly because it seemed like the uber kids just shot their special all the time, and were dead accurate with it. And you also couldn't play anything but the first artillery mode, at least for me anyway...well, on with the review:
Graphics: They were great. Very cute little characters, and the maps were well detailed. Only complaint I have here is that the water didn't move, but I understand that was probably because you ran out of time. Hopefully that'll change in the sequel.
Style: Very stylish, and just like worms. You'd make the original designers proud...or pissed off, because you emulated it so well.
Sound: There was none, and that was the major flaw I found in this game (after the bug fixes). Although you ran out of time in making this, so that really doesen't bother me a whole lot. Hell, I used to mute the original worms and play some of my own music anyway.
Violence: No excessive violence, exactly how it should be. Only blood I saw was the special attack of the final character you can earn, and that was fine. Once again, like the original worms, somewhat "cute" death animations, and nothing grotesque.
Interactivity: It was a game, so of course this score is high. I did find the movement of the game awkward at times, though, as sometimes I would end up in a wall or something like that. I also didn't like downhill movement that much, since it was trying to display their falling animations the whole time. Other than that it's great.
Humor: I didn't really find anything very humorous about it, other than the little characters and their animations. I'm sure a younger crowd would love it, though.
Overall, this was a great piece of flash work, especially for how quickly you made it. If there is any advice I can give, make sure the next one has music and sound effects, and thoroughly bug test it before release. It was great though, and I look forward to your future work. Good job.
