My Hidden Anime Room Good game but I think there are some bugs in it. I had to give up.
First one is the addition and subtraction puzzle.. the one where 1=3 and 2=1 and so on. even after i recalculated all the numbers it still didn't work.
next one is the red blue green door code. I put the code in exactly like the girls said them but they didn't work either.
last one what the where: "mount Fuji" I put Japan, Honshu, Honshu Japan and none of those work I don't know if I got that one wrong or not but just thought I'd through it in.
The Adventure?
