Hey!
I'm preparing an optimization because the actual spritesheet version is exaggerated in details. 

So:

• Quantity of frames: ~50% less
• Weight of the files: ~75 less (-90% less in some cases)
• Aseprite source file to help in management

The character #1 (considerating the paid version with 5 skins) have around 1400 frames (!!) so I hope finish this task in the next week.
This fix was based in the feedback of user Urborg. Thanks a lot!

Below, a sample where ocurred 90% of optimization:
