Okay I see! Admittedly the implementation for the drag and drop is pretty janky so I'll probably refactor that whole system and in the process of doing that, hopefully figure out why it bugged out for you!
As for the little guy not pooping when eating fries, I found out that I had made a slight error in calculating the adjusted probability (probability when carrots are eaten) when the little guy had more than 0 carrots collected. This basically made it so that little guy would poop 0 poops even though the adjusted probability was above 1.
Just pushed a bug patch (v0.1.2-alpha) and the pooping issue should be resolved.
Let me know if you decide to give it another play or find any more bugs.
Cheers!
