Thanks! Sadly, they can only be used within RPG Maker MV. As I only recolored them, the terms of the original sprites by whtdragon apply to these recolors as well. Here are their terms:
'Terms:
- As these are (mostly) edits of MV's sprites, you will need a legal copy of RPG maker MV, otherwise~~
- Credit is appreciated, but not required.
- They are free to use for commercial or non commercial.
- You are free to edit, change, recolor, re-edit, remix, maim, mangle, add on, divide, and conquer to your heart's content. I don't even mind if you re-upload them elsewhere as it would only mean more people get access to them and that is A-OK in my book'
