Hi there, thanks a bunch!! It kind of is, but as the license states, you can have a few exceptions and I’ve stated mine on my asset’s page: you can modify the sprites and then use them in your commercial projects as well; you don’t have to credit me (although don’t claim that the assets were made by you either!); and you can’t resell the sprites, even if they were modified (so like idk creating an itchio account and selling an asset pack with my sprites).
And yes, you can use it in your game! Although didn’t really understand what kind of images you want to provide in your internal data file? :”D
