Tough to say. I'd imagine that it probably hasn't been a full year and a half. However, it's been long enough that Germ has stopped asking the crusties if they've seen him. Unfortunately, Germ is an odd bird and I could see him giving up after a year or after a few weeks with equal probability.

The posters look relatively new, but that might just b ea matter of the art style. Honestly, you best bet would probably to be to ask the creators via social media and/or Kickstarter messages (if you are a backer.)
