I strongly advice all future runs to be recorded with higher gamma! Note that playing with higher gamma and recording with higher gamma are 2 different things, but I strongly urge any runners to do both, in order to better the playing and viewing experience of this game. How to do this is shown in the bottom paragraphs here, as well as in the Main Rules of the game

I hope I'm not alone in thinking that this game is too dark, and I don't mean that metaphorically, when I see let's plays or when verifying runs of this game, 90% of the time 90% of the screen is pure darkness. This makes the game unappealing and disorienting to watch, and weirdly enough straining for the eyes over longer sessions. Because of this, I want to strongly encourage all runners to make sure your recording setup records footage with higher gamma. Whether or not you also want to boost the gamma while you play is a separate issue, but I'd also recommend doing that too. This of course gives a decent advantage, simply because you're able to see more and scan rooms quicker, so there is an argument to be made that this shouldn't be allowed. But I have found the game to be much more enjoyable to run with these settings, and there's also no way as a verifier to know whether or not someone has played with high gamma on their screens, so to make things nice and easy for everyone, I'd encourage all runners to up the gamma on both the recording and on your screen while playing.

How to up the gamma when recording on OBS (do this before you record your run):

1. Right click on the source of your gameplay (usually either display capture or game capture)
2. Click on "Filters"
3. Click on "+" in the bottom left corner
4. Click on "Color Correction" and give it some arbitrary name
5. Put the Gamma-slider to the max (a value of 3.0)

This ups the gamma on your recording, but not on your screen while playing. If you want to play with higher gamma, you can follow these instructions to boost the gamma of your screen (Windows only):

1. Press the Windows-Key
2. Type in "Calibrate" and open "Calibrate Display Color"
3. Hit "Next" in the bottom right corner 3 times
4. Put the gamma slider to the top (or as high as you want to)
5. When you're done playing, set it back to normal
