Justin Pierce is stopping Kilroy & Tina – a very funny comic about an alien and a young girl that is currently running on Graphic Smash. It doesn't sound like burnout so much as the realization that K&T as currently structured could take years to finish.
K&T is often very funny and as a premise, it's excellent. (Someone correct me if I'm wrong, but it seems very original.) It's entirely possible after a break, Pierce will find another way to return to the project.
Fleen catches that it's also the end of Ali Grahamâ€™s HOUSD.
