It would be irrelevant to ask a question about a rando indie game in a space entirely separate from it. And indie games often don't have much of a community, especially not this one. Also, is it really entitled to ask in a comment section under a game (not the creator personally) how to delete some sprites?
Exactly, ever thought that the game that was shared with other people might get some response? Art immediately becomes up to public interpretation when it is no longer private. And why are you assuming that I want the creator to quite literally go modify the game to my preference, its so weird because clearly I am just asking how to delete some game files?
