I've been working trying to fix the 'trapped rat' bug. That is, sometimes enemies were trapped in the borders of the map.
The matter is that, trying to fix it, I've found a way to improve the game performance. You can compare the mean FPS (23.03) in this picture with the same stat in a image at the same point in a previous post (it was 18.07 but it was behind the stat screen).
Anyway, that means a 20% of game speed improvement. :)
By the way, I've also fixed some othe minor bugs like the one with Beth sleeping under the bed.
And, I've also added a new minor feature. If you look carefuly the image (it's actually not easy to be seen), you may discover it.
