First you roll. Next, if you don't land on the mouse position, the rodent.
So yes, you may let it catch up with you and win. I didn't really try to
make it look like anywhere near an actual mouse. One may imagine
an ambush if one so desires. If gets past you in it -- your bad luck.

Indeed, a mouse ending on your position after it's step is also a win;
wasn't so in original rules (my mistake).

A mouse is always "positive". Only way to move back is your "-10".

A mouse isn't a complex object here. All it can do is randomly react
on your actions, moving forward; or -- stay still. Like said, it's about
luck mainly, not tactics; a very simple thing.
