Downloaded it with no issues or signs of a virus. My Dell laptop opened it with no issue however some devices may scan it as a virus or an unprotected program simply because it is from itch and not Microsoft store or wtv other built-in program however, as someone who's downloaded the most random shit off of itch you can trust that this program at the very least is not a virus. 10/10 easy download and menu. If your looking for a site with sprites to add I'd recommend shimeji.org it is very easy to import any files as long as you have the correct file type. Thanks so much for this awesome program :)
