Q.1 Is the game ready?

No.

Q.2 Is the game lighter?

Maybe.

Q.3 Will the game have a mobile version?

...

Now some observations:

You may have noticed that the game page is changing frequently and may be changing even more soon.

The Fazbear's Fright part (night8/Springtrap's Night) is much more fun and more complicated.

The game has a completely redone new introduction.

The game has already been tested several times and one of them was on livestream.

The owner (@Angenylo ) didn't stop working on the game. He's only focusing on the new Five Nights at Freddy's Doom Mod Source.

Thank you for your attention and I hope to see you in the next post or at the launch of the game. Goodbye <3
