I recently downloaded the 0.562 version from the dev's fanbox, extract the parts, re-archive the game and performed scanning the archived I will upload with ESET, Kaspersky, built-in Windows Security on W10. I also scanned the entire computer with HitmanPro, Kaspersky, ESET, built-in Windows Security and Malwarebytes for precautions. No threats detected. I will probably use clean Mega account to upload to ensure nothing else can tamper it.
As of why I'm not using VirusTotal, I don't like the idea of uploading those files publicly, but feel free to do it yourself.
Not sure if that will reassure the concerns here, but most likely the file I will upload will be safe.
