1: Don't know if it's intentional, but you can not go trough between the house and rock wall (you can only go around to access that spot)
2: Maybe it's just me, but there seem to be to many sharp edges on the rocks in this location, looks unnatural in my opinion.
1: "unnatural" rock formation
2: "light-leaks" in the corners of tunnel and some floating "dirt" (parts of a texture I guess)
3: strange-"transparent" texture at tunnel area
4: another area strange-"transparent" texture at tunnel
5: confirming stuck location (got totally stuck last time, no way out)
