I had to reread your disclaimer at the very end of your description, cos I really couldn't believe this was made in just a week.
You really shouldn't play yourself down like that! Despite the simple premise, I'd say the story was very well written and illustrated. It still kept familiar elements from it's predecessor, but Liar Liar 2 truly expands on the story further, and I'd say there's even major improvements in the art style as well.I can't wait to see the remake of this, that's something I'm looking forward to covering once it comes out.
