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 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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

This is a simple program, perfect if you are trying to show someone VR that has never seen anything. The graphics are clean and the story is good. A bit interactive, but more like one of those slow rides where you get to experience wonderful surroundings. while the chair turns so you can see all the good bits.
A fantastic experience, looking forward to more of these
Idk why VR educational titles insist on force-stopping the action for the crap dialog to play out. Allow us to SKIP rather than just sit there. Also give us full control - no one wants to be a passenger in a cool submersible. Way too much restricted hand holding. We can drive and listen to the biology simulataneously. Stopping the sub every 15secs for a full minute is annoying.

It's not very long, but I really liked it.
5/10
Nice scenario with some scary moments. Underwater experience in VR can cause dizziness more or less, perhaps sitting in a chair than standing while playing would be more convenient in this case. The only downside of this project is the quality of the assets: very lowpoly, very poor textured for nonsense.
wow wish height was adjustable 9/10
7/10 Worth only at sale, as its a 30 mins. Sci-Fi cinematic VR experience. but the quality of experience is great, wish it was a full game. a note, using H265 or HEVC (10bit) doesn't help with color banding.
I would give 3,5/5 stars. Bought it for 2 Euros and it was entertaining.
The narration is painful, really ruins the experience for me.
