I'm not a gaming expert, but an ordinary gamer who just writes his opinion ;)
Doom is a roguelike, but a good one, with the same combat, interesting music, similar to Mick Gordon, but from afar, but still not bad
There is no plot at all, it’s immediately clear that the game was made for doom fans who decided to try something similar.
In principle, the plot is not particularly needed here
The game was created for those who just want to have fun running around the arenas, to good music, and with good gameplay
