Help I can't do the Bug Squasher achievement because I have one spider missing at the clockwork world. Can't seem to find it anywhere

看我游玩时长，无需多言。这游戏流程撑死6个小时，而我玩了快两倍时间了，我是真找不到27只蜘蛛，作者什么时候才能修复这个bug？这游戏我这辈子还能全成就吗？

It says to "Follow the nightmare" but I don't know what i'm supposed to be doing. The stuff isnt clear. All I have is a scrapbook picture and ice cubes. Theres a 2nd broken elevator but i cant find the missing part. and I cant remove the part from the first fixed elevator....

last play was 2 years ago, with 18 achievement without guide, now plan do second new game, for all complete achievement, does memories can be get back if passed that area? mean to back track to get, and any missable i need pay attention? i read those guide is too long for me to know this little info i need...

Why doesn't this have rebindable movement keys? How can I override WASD?
