This game is not a dating sim. All of the characters including the mc can die regardless of your romances. Character deaths only occur via story choices and explained exactly why it happens if you pay attention to the story.
All of the characters in the game have difficult aspects, including the mc.
Thanks for playing!
almost all of the cyberpunk and almost all of not romance focused games incorporate a complex world building and the concept of introduction of a specific technical terms, planet names, dimensions and etc. is common (at least of what I have seen and played on itch and steam). It is a quite some amount of info to go through at the beginning, but these details are what makes story more alive, readers more invested. soo...I cannot agree with you on that part
Maybe try to get into the mood for the story (it is not a dating sim where things happening around MC and love interest and focused on their relationships 70% of the time), and try to play with a game, make this choice and that, and just to experiment =)
