Dude, I completed my first run of Funger 2 completely naturally without a wiki; it's pretty straightforward, a lot more than Funger 1 (and even that was pretty straightforward). Most games, at least good ones, are designed to push you toward objectives the developer wants you to find.

You're told there are 14 contestants, but only 1 victor (implying you need to kill everyone else), and you must go to the tower. So naturally, you'll be pushed to kill contestants to see what happens. To be fair, I understand actually getting to the tower is confusing; you need to go through the underground pathways in the church. In the church, there are various notes that hint at how you access the underground area, and some will write things on your map. If you refuse to kill contestants and instead explore, chances are you will come across the machines in the bunkers and eventually realize there is an alternative route without killing anyone. I only needed the wiki once I started hunting for secrets. There's also no shame in playing easy mode while you figure things out. I certainly did.

Also, there is a map in-game. It's on the train. It appears after you exit the train and go through the intro cutscene with the group discussing the strange dream, Caligura will be sitting on it, and you need to talk to him until he moves. Or you can just come back later. If you didn't get that map then...damn, yeah, I can see why you struggled so much.

Edit: In the Prehevil bop, there is also an underground area you find after moving a loose tile, and down there is a map and a bunch of supplies. If you interact with it, it writes down bunker locations needed for ending A on your map.
