A Commendable educational message... but...
I thought this flash might have benefited from some more entertaining visuals. Although I understand you trying to make the flash as factually accurate as possible (which it was) I think any flash on Newgrounds must be made with the understanding that viewers are expecting to be entertained. I see no reason that your flash couldn't of contained the exact same information, but have much more entertaining visuals (like lava pushing it's way up through the earths crust). Even the island forming, although entertainingly shown could have been done even more entertainingly.
Say are you still planning on doing part 2? I doubt it with how busy you are. You were planning on showing ecological succession on an island, right? I don't think I told you this but I'm a forestry major and I might have fun doing a flash showing that... maybe that could be another project for us down the line?
