Cute game! It took me a while to get the hang of the controls but I really liked it. All of the different endings were interesting.
I think it was less an issue of the timing and more that I didn't understand what everything represented. I didn't realize that the bar in the middle showed what Rodney wanted to make, I thought that it showed who was getting suspicious alongside the faces. I don't know if It's a huge deal, though, I figured it out in time to get all four endings within 15 minutes or so.
