It's kind of amazing how some choices made, writing wise, are somewhat puzzling, but the mystery of it is oh so tantalizing.
Spoilers ahead!
I think it's a good start but the break neck pace has to slow the fuck down. In a span of a couple of days we make a friend from a guy whom we should not trust at a glance even tho he's very friendly. Sure, narratively it doesn't make sense one bit for him to be the killer but to so easily trust is foolish at least and dengarous at worst.
My main problem, however is with the worldbuilding and it's consequences.The concept of fruit and vegtables is not lost over a couple of thousand of year and a voyage to a new galaxy? and then the f-slur during the halluciantion, that might not be hallucinations at all. It's a nit pick but it really undermines the believability of it all, in my eyes.
All that being said I honestly wish to see the end to this and hope for the best in the future updates!
