i am in windows 11 and i cant run it, it says that it might be a virus
Yeah, I believe it's a popup saying it's from an unknown source, meaning you need to click more info then run anyway (Assuming it's the same popup as in windows 10). The popup should appear for most games you download on itch.io, since all it means is that the game hasn't been officially recognized by Microsoft (Which doesn't make sense for a 48h game jam).
