This has potential

Hahaha! I never expected anyone to make a Sai dress up game! I like how the face is customizeable. A little bit hard to align the pieces you want though sometimes. Maybe clothes for the next one?

Ok for a start

All the interesting dress-up games I've ever come across have a good system to manage parts and accessories--like slide-out panels to hold different types of parts. A good management system will keep the window from looking cluttered all the time.

And parts should snap into place on the character. And you need some kind of background music--that you can turn on and off.

It's not too bad for someone whose just learning Flash.

One major thing missing.....

Ok idk who or what Sai is, but if you want to be sucessful on newgrounds making dressup games, add nudity, i know it seems kinda odd but thats just how this website rolls, look up the "how to do flash" videos on here, most of them tell you how to draw tits.
