Glad you enjoyed it!
Unfortunately, we're nowhere near having a release date for the sequel. If we're lucky, it'll be by the end of this year, but it also might not be until early next year. I wish I could give you something more certain, but since all the art is done by one person, we're generally subject to his schedule.
In the mean time, we're releasing other games with different artists. Our next fully voiced game, Born to Breed, has a free demo out now, and is expected to release within a few months.
