Thank you for the heads up! I'll push out a build to fix this right away!
No problem! Also, I did want to inquire about a possible add-on to this or even a separate tool-- A splitter of sorts. Something that would split each animation in each direction into individual horizontal strips.
I would happily pay for something like this.
Having each animation split up is the only way to get this character base to work comfortably in GameMaker. I have tried Seliel's original atlas as well as your combined one and there just isn't a viable way to make them work. ;(
