Everyone complaining about the final boss must not be very observant. The snake follows a very easy pattern, and it has already been improved (as pointed out on the Newgrounds submission). A great game, even after playing through several times. 5/5!
Not a bad concept. However, I think as far as web designs go its fairly basic, but there is some potential here.
I must say it is rather well done for designing a page in flash. I will stick with my XHTML and CSS though... I can't wait to see future versions.
