Is Kotonoha Island safe?

Foundplay checks its link every few hours and gives it a daily safety check (malware blocklists, downloads, crypto miners, parked domains and fake virus warnings), and hides the game at once if that check fails. No check can promise a site is safe: if a game asks you to download something or for a password, leave it.
