Thanks peoples. I didn't use spriter, I started working on this in June 1 2012, before it was around. I don't know what "pin" is, I just manually animated half of it, and set positions with the rest.
I've just bought it on your website, and congratulations for the steam featuring.
I just want to know, graphics look crisp and vectorial, really nicely done, what resolution did you choose for your game?
