Funny Room

Mr Johns, a wealthy and powerful businessman, had retained a childlike soul. He sought people who could build him a fun place to forget the worries of his everyday life. He eventually found a team that offered to do the work for free with the condition of finding 4 hidden keys within a set time or else disappearing forever. Mr Johns, loving challenges, accepted and disappeared forever. To avoid ending up like him, you too will have an hour to try to find these 4 keys. Good luck!
