These are some pretty nice platformer assets. However, the stipulations in the readme file conflict with the licenses accepted here:

Prohibitions
* The asset may not redistribute, lease, license, sub license or offer this asset to any third party "as is" or as a separate attachment from any of your work.
* The asset may not be placed on any website in a complete or archived downloadable format

Under the licenses you've selected (and any other license accepted on OGA) people are allowed to redistribute and offer the asset as is to others. Ironically, this page is already in violation of the 2nd stipulation. You've placed the asset on a website in an archived downloadable format.

Would you be willing to remove those stipulations from the zip file? Until then, I must mark this as having a licensing issue. Please let me know if you have any questions about this.

No problem. :) I didn't mean to sound angry. I wasn't. That big wall of text was meant to explain, not chastise.

Those stipulations suggested by your friend are fairly common, but often either legally unenforceable or they make the assets unusable. Of course they're meant to promote freedom, but they unintentionally cause legal conflicts where any game that used them would be in violation even when the game is free and open source.

I can explain why if you would like to know, but these are all good, so I'll stop typing. Thanks for sharing these. Looking forward to seeing more of your work!
