Thanks for the feedback! The squirrels going out of bounds was something never prevented, as I was still trying to get the hang of Unity. It is on the todo list for the next update though.
As for the page menu and cursor problem, I've attempted to fix that, and did a small amount of research, but am unsure how to fix this yet.
Once again, thank you for the feedback!
Edit: both have been fixed, there will be an update tomorrow sometime between 1:45 A.M. and 4:45 P.M. EST.
