Widget, I didn't see your edit until now. But that's a wonderful compliment!
The game engine was really crap, even though it was a great learning experience for me. Building on it would unfortunately be a no-go.
Pen painting everything by hand was mostly slow, I think. I have great hopes that we can make something with that painted look, eventually! We just need to take more clever shortcuts, perhaps like in Aquaria. But I have no doubt that pen's art will find it's way into published stuff eventually
I'm hoping to find time for a new, proper project during this spring. Hopefully we won't disappoint you again
