I can assure you that it is not a scam and there's a user just below your comment who were able to download and play the game properly. I created the setup file using an application called Inno set up compiler. If you can provide me some more details and screenshots I'll be glad to help you out.
Oh that, yeah I published this last night but today I uploaded a new version but forgot to fix a bug that prevents the player from finishing the game so I moved the game back to draft and then uploaded the fix. Then I published it again. Sorry for the confusion, I assure you that this is not a scam or a virus. I'm new to itch.io If you need further help let me know what I can do to help.
