1-Are these sprites and songs for commercial use?
2-I would like to see more enemies.
3-I would owe a yoshee mount.
4-I would like to see the phase selection in 3d.
If you can do what I'm asking, I'll buy your art.
Hello! Would you like to send me a private message with some further detail? Particularly on number 4. As per number 1, here is what the store FAQ says:
"Commercial Projects
In summary, one purchase of a Royalty Free licensed asset allows you to use the asset in one commercial project. If you wish to use it in more commercial projects, you'll need to purchase the asset again for those projects.
Non-Commercial Projects
If you purchase an asset, you're permitted to use it in unlimited non-commercial projects. Please refer to the license itself for exact definitions.
Don't forget, if the item has an exclusive price and you decide to purchase it at that price, you're permitted to use the asset on unlimited projects."
I would be happy to work with you to supply you with some custom functionality and artwork - just shoot me a message!
