Oh indeed, from your screenshot it should be Mha, not Mhe! That's something I need to fix asap when I get to work on this project again. It's surprising that other people could finish the game despite this error, I don't know how they found out the correct words to enter...
It's true that the font doesn't make it clear which is a R and which is a N. That's something someone else noticed before, I'll try to fix it too.
Thanks for playing KaosKahn, and for the feedback!
