Generally speaking, people like to see some sort of feedback in a game when they do something. It's an interesting gadget, but not overly entertaining.

P.S.: How do I know if I entered a valid number?

This game had a decent idea, good (although little) graphics, and fulfills its purpose. There is no reason whatsoever to give this game a 0. The game at least works and deserves better than nothing.

P.S. I completely agree with DavieR2D2, this is a good concept, but its not really NG material.

This has some merit, but that saying, I agree with most of the people here. This is not a Newgrounds thing. I would enjoy it in other places, like for instance Slashdot or something, but not here.
Also, don't tell people not to say bad things about your stuff. Constructive criticism is important!

If you think about it, he has a good idea going there. Most people will not enjoy this because it is not entertaining at all, but this was a great idea and a good way to practice action script.

theres not much to say, a really bad and boring game!!
