About COSMONAUT

COSMONAUT is an immersive story-driven horror platformer set two centuries in our future. Suit up as Jarobi, a green DSR (deep space reconnaissance) contractor tasked with boarding the S-class research vessel, Diogenes. Lost 80 years prior in the vast Kuiper Belt, the vessel has become an iconic symbol of humanity's early manned voyages to the outer solar system. The ship is for the taking, but at what cost?

Creatively explore a decrepit futuristic environment via unique movement mechanics, free from gravity using any surface you choose. Survive the dangers of deep space habitation through various puzzles and challenges. Arm yourself and choose to merely defend against, or fully exterminate foes of both extraterrestrial and artificial origin. Put your psychological resolve to the test and become the first to unravel the mysteries surrounding the lost Diogenes vessel.

COSMONAUT is an okay Indie, adventure game, okay then story. In the far future a scavenger vessel is on the lookout for the missing Diogenes, an s-class research vessel that disappeared 80 years ago in the vast Kuiper Belt, the vessel Diogenes had not just become an iconic symbol of humanity's early manned voyages to the outer solar system, but it has now become a treasure trove for all scavengers across the solar system. And this scavenger team has been able to find the lost spaceship but who knows why it really disappeared, perhaps that treasure trove of a spaceship is more of a floating coffin in the dark vastness of space. Now let’s go into the likes, the story is good it takes some inspiration from other works of science fiction horror games like Dead Space, the story does have some obvious twists that you will probably see coming, but they still did something with the story that I didn't expect. The notes for the story was good as you know I like notes in video games as they can help with the world and there notes do a good job in that, although there's a slight problem with them and the story itself but that’s for the dislikes. The gameplay was okay you basically have a k…

Игра «COSMONAUT» – это захватывающее путешествие в космос с элементами выживания и головоломок. Графика стильная, с яркими цветами и атмосферной анимацией, что добавляет глубины космической тематике. Геймплей сочетает исследование, управление ресурсами и решение задач, требующих логики. Сюжет развивается через диалоги с AI-персонажами, что делает историю живой. Звуковая дорожка усиливает напряжение и эмоции. Минус – иногда сложная механика и недостаток руководства. Однако для любителей инди-проектов с философским подтекстом – обязательный выбор.

Not recommended Oct 20, 2024
The start was nice! Very atmospheric, ok controls, interesting movement mechanics without being too complicated. Then, I pressed the start/pause button on my joypad. Possibly 0,5 seconds too long. I've been thrown to the main menu, lost all my progress (about 25 minutes into the game). I recommend to try the game, but don't press start/pause on your joypad until you get a confirmation that your progress is saved.
