Nice effort
The game needs a few touch ups (more excitement, for example. The game is unfairly boring) but overall it's a good effort. Obviously you know your actionscript very well. To program for this must've been a pain in the ass. Graphics were outstanding but could still use a little improvement. The purpose of the game was kind of unclear, as i found myself wandering ahead with nothing in front of me other than clams and bubble fountains... Figured it out after a bit, but if i was dumber than smart i would've not understood it. Remember to make your games more idiotproof (as there's a lot of idiots out there who'll mark you low because they think "the game sucked") and meaningful. Overall it's a good game though. I'll give you that. You get a 3/5. It'll help your game survive and perhaps you can improve it so that next time i play it it'll be that much better ;)
Very good effort! Keep it up!
