I get what you mean about the name stuff. I'll consider whether or not I want to commit to adding separate dialogue for it (there's currently quite a bit of dialogue about switching names back and forth, and a bit more stuff tentatively planned). I'll have to think about it.
Thanks for making me aware of that.
There are some objects that I INTEND for you to be able to interact from multiple sides (signs and chests for example) because I don't really see the point in preventing it. For example, I'm not sure a text box saying "you can't read the sign from this side" really improves gameplay.
However, in cases like the one you screenshotted, where you definitely shouldn't be able to open something from there, that definitely needs a bugfix.
The invis solid tiles there are actually a leftover from earlier in development. You're right, I should probably remove them. :)
