Hi Joshua!
It's going to be difficult to increase the space between the lines on the front, but I'll look into correcting that on the back, where I have more free space.
The second set of stats is for rats or bats, at the GM's discretion. Whether they are rats or bats then becomes a matter of personal preference, depending on which will induce the most terror in the players.
Oh, I mistakenly pluralized "weakness"! I'll take this opportunity to come up with a second weakness.
Thanks for your feedback!
