(UPDATE: So I grabbed the game This will take a bit) So This Game Was My whole Memory I just remember this game in like 2023 "I LOVE THIS GAME ITS SO FUN AND SO SCARY!" Then in like maybe 2025 it came back so fun and stuff. Then in like 2026 or late 2025 It said I'm in a old version.I cried that this game was gone. Then Today Or Somthing, I know how to make revivals so just to say this game is coming back by me, well I don't know if it will work so yea. Wait or look at this review until there's a link to the revival. META WHEN I'M GOING TO PUT THE LINK, DO NOT REMOVE THIS,the fans of the game will love this!

I remember playing this game back in 2022-2023 but the game hasn’t updated since Halloween of 2023. The devs have started to work on a different game and the servers are down in CatOS. I’m starting to believe CatOS is never coming back.
