Hi! I totally understand the issue with overwriting the default character sprites and I'll surely also add an optional dependency on your mod.
just tell me if you'd prefer that I poke this thread or if I should create a new thread in the minime mod page, when I'm done.
By the sound of it, it seems like I will have control over the character prototype stuff so I don't think I need to ask questions about replacing attributes, particles, sfx and anims in general for the custom character.
I don't know if your mod does anything to replace the rendering for the jetpack mod, though. But from the minime description, I'll assume not much is done. So, I'll surely just disable all my jetpack compat scripts when minime is active with an option to re-enable them in case people want this character to override the jetpack rendering anyways.
