To the west of the 5 skeleton warrior room, a chamber full of bats appeared, and the doorway slammed shut behind me. I had a key, I could have ignored them, but I wanted to know what would reveal itself if they were all slain. It cost me dear health, but the chamber door opened.
I was using gifBrewery because I knew how to resize a gif with it quickly. When I’m not cropping a to an artistic subset of the image, doing the whole process with the handful of lines of ImageMagick needs goes much more quickly.
Notice the use of mogrify to do the batch process at the beginning… That was the tricky part.
