Artists will be pleased to hear that I have just released SpookyGhost as a free and open source tool! https://ncine.handmade.network/blogs/p/7850-spookyghost,_a_procedural_sprite_animation_tool,_is_now_free_and_open_source#24494

SpookyGhost is a procedural animation tool for sprites that was previously a paid application. I have added new features, corrected many bugs, and released it on GitHub under a MIT license.
