A very short (2 hours playtime) story in a special and beautiful world, in a colorful underwater empire. Really-really very spectacular! You can float, swim freely around, but you cant die, you can just watch the plants, the colorful fish. Its calm and peaceful. Of course you have a mission: activating crystals to free a little green ghost, who will show the way to the next area. To activate those crystals it is necessary for your the hero (a little purple ghost) to posess fish, what swim around. Different fish have different skills: one brings lightness to the dark cave areas, other eats sea urchin and thus open up the cave entrances, another again is strong and can swim against the currents, etc. Recommended!

Cute exploration game. Controls play best with a controller - having tried both ways. If you can't move with controller at first, and you see the mouse cursor, click in the game window with mouse once first. Store page blurb text should really say "Controller Recommended". Played on Medium graphics settings, and was only about as clunky as I'd expect a slightly slow, non-agile, jellyfish swimming to be. ;) (Remember to use BOTH joysticks - left for movement, right for camera, use both while rotating) A good buy on sale - I got it for 80% off. At time of review, I've unlocked 2 of the seemingly 4 different fish. Cons: only one save-file & no confirmation dialog - so be careful not to select "New Game" instead of "Load Game". I confirmed this when deliberately re-starting after my first 8 minutes. (out of 26 minutes total at the time of review)

planktOs is a tranquil indie exploration game developed and published by Blot Interactive, and it distinguishes itself through a calm, almost meditative approach to gameplay that places atmosphere and discovery above challenge or spectacle. Set entirely beneath the ocean’s surface, the game casts the player as a small, luminous spirit navigating a coral-rich underwater world that has fallen into imbalance. Ancient Elders, once guardians of the reef, have been imprisoned in crystalline structures by a creeping corruption, and while the story is told sparingly, the sense of purpose is clear: explore the depths, understand the ecosystem, and restore harmony to this fragile aquatic realm. The world of planktOs is its greatest strength, presented as a broad, interconnected underwater environment that encourages slow, deliberate exploration. Movement is fully three-dimensional, allowing players to drift upward through shafts of light, descend into shadowy trenches, and weave between reefs teeming with plant life and marine creatures. The visual design leans into vivid colors and soft lighting, creating a soothing contrast between safe, vibrant areas and darker zones tainted by corruptio…

Short, different, chill game.

Games like Undertale that remember what you did

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
