Awesome!
I love the cohesive style you have going here and the fact that you hand draw everything.
It looks like a high quality, polished product and more importantly a really fun game. <img src="smileys/smiley1.gif" border="0" align="middle" />
On another note; I recently bought myself a Motion Computing le1600. It is a tablet PC that a lot of artists have been adopting over the past few years. They are a little old and not incredibly powerful but they have a Wacom Digitiser built in and they can run Windows 7, Photoshop, Artrage, Paint tool Sai and Mypaint.
It might save you a bit of time and they are pretty cheap on ebay.
