Surprisingly engaging and atmospheric. It's clearly a love project of the developer. I thought it would be boring at first, but although there is no action, it's still very intriguing to play. At its core it's a narrative adventure in which we follow the main characters in her dives, which are guided by two other scientists and focus on the whale family the MC is following. The game sucked me right in with the second dive. Very immersive. The main story is very short though, but you can repeat all the dives and explore to your liking.
