We tell you who should skip it, too.

Play it if you…

Good fit
  • Adventure players who want an aquarium setting rather than a conventional fantasy or urban environment
  • Players who prefer investigating locations and speaking with characters over action-focused progression

Skip it if you…

Saves you a refund
  • Players seeking extensive combat systems or sustained shooting, since those elements are only occasional

Our take on RONNARIUM

Rather than centering on combat, travel, or a conventional dungeon structure, this adventure replaces them with aquarium investigation. Its unusual setting, creature conversations, and two-outcome structure make the rumor itself the main progression framework.

What is RONNARIUM?

RONNARIUM is a 2D adventure game set in an aquarium containing a huge tank of the same name.

Yocto visits after hearing a rumor that nighttime visitors become divinely bewitched. Exploration covers the public aquarium and its rear areas. Players investigate points of interest, speak with creatures to learn about the rumor, and search for a key to a room containing a clue. The game also includes conversations and interactions with accompanying characters, along with occasional mystery-solving and shooting elements. Movement and examination are the basic actions. Choices affect the outcome, with two possible endings.
