I love the bats! Very cool looking!
But..
I woud love them as an image that I can plop down during game. Mainly because the way it is now, the players will be stepping on the bats while they make their way around..
The bats really should be above the player tokens.
Which brings up the question: Do any VT's allow for that currently? I know Maptool does not yet but will in version 1.4. Just curious..
