Yeah, hit up YouTube, look for tutorials. There are some great guides to things you really should know (the game's tutorial is minimal at best) and handy tips for crime solving. Some of this stuff you can figure out in game with some intuitive leaps, like looking for security footage, or checking sales ledgers in stores to find out who bought a murder weapon. Other stuff is a little more obscure.
The game is still early access (or only just recently left it) so you also probably ran into some bugs. There are/were some missions that just spawned wrong and couldn't be completed.
Frankly, I think this is a very good thing. One of the worst things to happen to roleplaying was a generation of GMs thinking they have to be Brennan Lee Mulligan or Matt Mercer.
Stop worrying about how marketable your game is. Stop worrying about how good your writing and your performances are. Roleplaying games are, by their nature, intimate. Every single game is an experience shared between a small group of people. And that's exactly what makes them so powerful.
I've lost track of how many times players have literally cried during my games. I'm talking "Grave of The Fireflies" kind of tears here, not "My GM is an abusive dick" tears. Just the other day one my players told me that I'm the reason they can't listen to a particular song without crying, because it reminded them of a particular moment in one of my games. And that's the sort of thing that makes you think "Holy shit, I should be recording/livestreaming this." But if I did that, none of those moments would have ever happened, because my players aren't professional actors, and they would have been so self conscious about performing to a crowd that they would never have lost themselves in their characters like that.
Enjoy the intimacy. Enjoy the imperfection. There's nothing else like it.
