You are not the “author” I am.
These are not FREE they are useable (not distributable) only if you own the Spriteforge PRO application. (available from my site)
I will be happy for them to stay but please either credit properly with a link to Spriteforge in the description or remove it.
The following sprites were removed due to copyright issues:
Sideview walk spritesheet for platform games.
Sideview jumping spritesheet for platform games.
Isometric spritesheet animation with walking robot.
