I agree that the instructions would have been really good to have throughout the game--I didn't even notice there was more below until a few minutes into playing, so I was pretty confused at first. But it's really creative and I liked it a lot!
I thought it was a really creative idea and it was interesting to use code, but it was a little confusing figuring out that I could control the code on the side--just a little more clarification of how it works and I think it would be awesome!
