I say upload a new project asset with just the monster files in there and set the price and now you have two options available.
Ohh! Now I got it, but there is no reason i upload another project, just gonna low the whole project price and put to rise only if the buyer get the "player sprite sheet".
Done!
All right I made the purchase. One more thing it would be lot more organized for me if you put the files in 1 folder.
sorry for make you wait, already changed the content to zipped folders, enjoy!
Thank you!
