@Mike:
Well, if you once has a plan to set some discount to Spriter, please inform me, I will act quickly.
I need a motivation to buy this, especially I have only pretty limited budget.
[EDIT]
NVM I bought it from steam as I just get a stable router that can guarantee stable 24/7 internet connection, that helps and I decided to buy Spriter, it's a cool program!
BTW, if you're interested, I'm playing a game dev tool called SuperPowers, another HTML5 game dev kit, if one day it has support for Spriter that'll be pretty nice.
