Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 22 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Biolum is a 30 minute narrative experience with light interactivity.
Biolum brings us on an immersive mission into the deepest depths of the ocean to explore the abyss through the perspective of scientific researcher Rachel, voiced by Dominique Tipper (The Expanse). Rachel is guided by expedition leader Eva, a renowned marine scientist, played by Charlotte Rampling (Denis Villeneuve's Dune). As we discover the mysteries of this bioluminescent VR underworld, it becomes clear that this relationship is not as simple as we thought…
Rachael discovers that a luminescent parasite is infecting the ocean flora and fauna. Glowing hybrid underwater oddities swim around us as Rachel and Eva try to understand the scientific meaning. The beautiful bioluminescence is wreaking havoc on the natural ecosystems. How could this have happened and what does it mean?
In this VR story, nothing is as it seems. What’s beautiful very quickly reveals itself to be contagious, and perhaps more dangerous than ever imagined. As Rachel gets infected by these parasites, she faces a mesmeric fight for her mind and body. Inspired by the beauty of deep sea life, Biolum blurs the lines between biological truth and sci-fi and taps into existential themes and cosmic wonder of the great unknown.
Light interactivity woven throughout that advances the storyline and encourages you to become Rachel and immerse yourself into her exploration

A fun little VR movie, very little interactions, but you do have a flashlight. Not a lot of different locations, but well worth it in a sale.

At first, I was really interested in this deep-sea themed game. But after playing it, I realized it was just an immersive VR experience without any interaction with the environment. You just keep listening to two characters talk the whole time. The character you play as starts out normal but becomes increasingly strange, and the ending makes no sense. The only thing I can recommend is that it truly gives a deep-sea feeling. But everything else, I wouldn't recommend. Immersion: 100 Scene Interaction: 0

It's a pretty ~30 minute story with some interaction. A walking simulator if you will.
This was a really cool short experience. I would recommend it on sale or at full price, because a lot of love went into this and I'm sure making a VR game isn't easy. I love anything ocean related so I had to try this
Its More of a Ineractive VR Movie than a VR game. Nice experience to explore under water. Option to explore outside rail movement should have been great .neverthless decent experience Its the Easiest game to get 100 % completion. lol
Рекомендую зі знижкою. Зайняло всього 30 хвилин і таке відчуття, що половину того часу я провів просто слухаючи розмови персонажів і дивлячись титри. Це було би ще нічого якби ці розмови відбувались під час руху, а не треба було просто чекати на місці поки вони закінчать свій діалог. Зате вся фінальна секція і загальна розв'язка мені сподобались як візуально так і сюжетом.
Very enjoyable game. Mind you its only 30 mins so you probably have to grab it on sale. Story is great and design is beautiful. definitely recommended
TL;DR - It's a good game idea, but nowhere near enough. Picked up this game because it sounded fun and had some fun implications. The VR controls are ok, but exceptionally simplistic. Unfortunately, the pacing is almost ridiculously fast. It plays more like a game demo than a game itself. There's also the problem of setting up the space to work well with VR. You can easily be looking the wrong direction when X happens because of the way of setting is orchestrated and being distracted from looking in a given direction. All in all, it's a good start, but feels like it needs to take a page from games like SOMA and some VR cave games to make it great.
