Dude I love these, a few of your characters were a very close fit for what I wanted for my game, so I'm using them in the mockup artwork! And also in the prototype to save me time.
Was a bit confused for a while until I poked around - maybe add a note that you need to download all 3 files and combine their contents together. I figured I just needed the latest one - 1.3. Turns out it only has the attack anim. I thought that's all there was for the longest time until I came back here today to double check!
I will need to credit you in my tweets when I start posting GIFS of the prototype. These are so useful.
