Talk about a late reply but if I remember correct you look at the animal horns hanging on the wall downstairs and compare it to the box upstairs on the bed.
Late reply but yes you are missing small details. Just check the source of the code again carefully and compare to the box and you will catch what you missed. If you're still stuck, the dev has answered the question here in the comments.
It opens. Go check the code again, you are missing small details. Same thing happened to me, put in the code and it didn't work. Looking at the box, I realized the code I thought was right was wrong then had to go check code again.
Cool game! Didn't think I was gonna be able to escape from Jig but I finally beat it. I had 1 or 2 items in my inventory that I felt I either didn't use or should have been thrown away after use but maybe I just missed their purpose. Really cool game though.
Camera just spins in circles on the remastered version on Windows 10 for me. The Legacy version works but I couldn't figure out what to do at the big Dominos crates after jumping across the rocks in the water, so I quit there. Seems fun though.
Well that was fun and simple. The moth came out on its own lol. Edit- I tried again and same thing happened. Moth wiggled out before I could even get the hook in.
