Thanks for playing.
It is possible to move beyond the altar. It is a minor puzzle - perhaps a bit too obscure though.
Read the text when you click on it carefully, and consider your options.
I think the challenge with that puzzle might be two-fold. I restarted the game three times, and saw your comment here before I realized what I had to do.
Part one is the riddle itself. The challenge to it is that depending on what words you emphasize in a sentence it can completely change the meaning of the sentence. But hey, that's fair play, it's a riddle and that's obviously meant to be the challenge.
The second thing that I think makes it maybe more obscure than intended is I don't think it's obvious that the riddle even can be read in the intended way, because the tutorial directions for using dice might lead someone to think that dice only interact with the action menu - although I have no idea how to solve that without either making it too obvious or changing the game mechanics entirely.
