Thanks!
I have fixed some of the bugs you mentioned like the door at #8 and the wolf eye lighting at #29.
Also really thanks for the help on the Audio Mixer issue, it already confuse me for quite a long time and i finally fixed the bug.
I will also make some adjustment to the slime and wolf to make them more balanced in general circumstance.
For the last one, one of the slime spawn points is set under that obstacle on purpose, as a little joke :D
