1 Million Players!

Yesterday Portal: Revolution hit the 1 Million player mark! I mean what a milestone. Round number, satisfying to write...
Thank you all for playing, and for the immense support you've been giving us.
Fun fact: 1.000.000 individual people have now actually downloaded and launched the game, but it's been added to 2.500.000 Steam accounts. That means 1.5 Mil players still have not launched it once! Come on you guys! Give it a shot!
Well, again thanks for the continued support!
But you know what? 1.000.000 is just an arbitrary number anyway. It's entirely based on our base-10 number system. Who is to say that any of the other numbers along the way are any less meaningful?
So screw you player 1.000.000, I'm going to celebrate player #403.200 now. If you happen to be player #403.200, please reach out. I have no way of knowing. We unfortunately didn't invade your privacy enough to do that.
Alright then, back to work.

Developer commentary
Added full developer commentary from most members of the team, featuring over 200 nodes.
Engine
Volumetric lighting
Updated volumetric lighting effects to require less samples, which improves performance while also looking better. We could measure speedup of up to ~46%. The new implementation also allows you to select different quality options and their look has been improved to work from more view angles

Map changes
We updated a lot of maps. Besides the usual bug fixes detailed below, here are some of the highlights

Low quality graphics settings

Some materials would also fail to respect lower graphics settings and render at full quality. Some commonly used models will now render at lower fidelity when low graphics settings are enabled.

We're preparing the release of our official Soundtrack. Seeing all the amazing fan-art inspired us to involve the community with creating an album cover.
Submit Here
Submissions are open until March 29th
https://forms.gle/YaES2yACK9Daaa438
A Google-Account is required to submit.
Contest
One artwork will be picked as the key album art, which will be displayed most prominently.
If there are enough submissions, we may pick 4 act-specific or 8 chapter-specific album covers which will be embedded into the individual music files throughout the game.
Other good artworks can be chosen as secondary album covers which will get displayed in other places like the Soundtrack Steam Store page or YouTube Video releases.
We want to encourage artists to submit as many artworks as possible! We want to honor as many submissions as we can. Everyone can be a winner!
Guidelines / Rules
These rules must be followed for a submission to be eligible

NO AI IMAGE GENERATION!
No human depictions of Stirling or Conly (We love seeing fanart like this but we don't want to officially lock in a human look for these characters)

Submit at a minimum of 1500x1500 pixels resolution
Image must be perfectly square
Best Practices
Here are some hints to what we're looking for. Feel free to experiment and be creative, these are just some pointers

Make sure the cover is somewhat readable when scaled down a bit (No need to optimize as much as for a logo though)
Painted / Drawn artstyle. Avoid 3D renders or styles like it
Illustrate a moment, character or object that made an impression on you
PS: For those wondering, the authoring tools and map sources will be released soon after the contest.
