Move the mouse to make the sprites point in a different direction. Click and hold to use the walk animation. Use the slider to adjust the frame rate of these sprites, though you will need to restart the project. It appears that these sprites were designed to be run at 6 frames per second, though you can speed it up or slow it down to whatever you want.
I used my Spritesheet Splitter app to quickly split the @pinkumbreon's spritesheets into individual costumes as well as apply the alpha (transparency) channel. This app automates the process of manually cutting up spritesheets, adjusting the alignment of each costume, and removing colors that are supposed to be transparent to name a few of it's key features. A download for the app can be found here: http://thistle4everfree.wix.com/anvil#!splitter/c1qwp Although part of the process was partially automated, some manual changes were necessary for the walk cycle animations, not to mention the scripting. A few minor edits were required to make sure that the animations looked correct. For example, two of the sprites had only one frame where their right foot was in front of the other. These costumes needed a flipped counterpart to display their left foot in front of their right foot.
