Hello!
The game was playtested on Ubunty Linux, and it worked fine. Although it could be some kind of bug. Do this bug occurs if you're loading older save (made before explosion)?
The bug only occurs during the explosion event. I haven't tested the previous saves, only the last one before the explosion, which allows you to play it again but always gives the same black screen problem after the explosion.
I left the Linux I was playing on and went to play on Windows because Linux gives a lot of problems, so on Windows I was able to play the game without any problems.
I played on my laptop a Sony Vaio with:
i5 3337u (using Intel HD 4000)
16gb ram
I don't think the problem is the hardware, even though it is below the requirements, but maybe something related to the hardware added to some Linux driver that I was playing? Anyway, I tested it on Linux Mint and Pop OS, both gave the same problem (which must certainly be some critical error not shown in the game to the point of preventing its continuation). On Windows it worked perfectly and I was able to continue the game normally.
