cool game, I am jsut replaying it right now.
It's jsut that stuff is really well hidden and there are ways to go everywhere so finding which the very next place to go is is kind of har, partially due to the lack of any sort of map.
like currently I got the keygun and the feathergun and after tons of searching everywhere the only availlable place to go seems to be the desert to the left.
which however has enemies that are ALL like 20 times as strong as any other enemy ever (every enemy before was on the same kind of low level and these are like 500 damage done by a single hit. which reflects in that the weak enemies gave like 5 expp and these one give like 150 exp)
jsut too hard, given that you cant even avoid most of their attacks.
so yeah, no idea what to do, except grind exp to get string enough to somehow tank through it :-/
