I didn't hear any sound or music, I don't know if that was intentional or not but i think it may have added to the feeling of it being a bit slow with the text.
I like puzzle games like this and it is a good concept but i think maybe it takes a little too long to get into and the text is far too slow, but like i said previously, that feeling of it dragging might be due to there being no sound.
I think the idea is solid, just needs a bit more fleshing out and polish.
