Thanks for playing.
Your feedback does echo a lot of the same issues other people had. At this point I'll have to nail a sign that reads "beware the pathfinding" to my wall.
I need to come up with more ways to subtly guide the player in the right direction. In particular, because I'll open up the environment more later. Currently the only indication that a tunnel is near are the wooden beams and the light rails.
I wasn't sure what to do with the skills if the player has the wrong weapon equipped. If they got unequipped automatically I think that would be annoying but maybe the problem will fix itself once there are more reasons to visit the stats screen.
