Thanks! I don't know really. If I had any grand ideas, I probably would add them. This is one of my games with the most plays so it's not out of the question that I will update it some day.
Yeah, I can see why it's the most played! Although, I just played Arithmometer and I like it even more than this XD. What are the main sort of mechanics you would add if you could? I'm interested to see where this could have gone if you did update it/do in the future!
