Hi, lillyfox. Due to the many changes (almost a new game already) and the fact that old saves will no longer work because of it, I will no longer release it as an update but rather a new game probably named Zodiac Hunters 2 (name not final as I'm also considering the opportunity to change the title). Owners of Zodiac Hunters will get a free copy (more details when it's released). The planned release date is early April (looking likely but not final as well).
