Seven Nights At Rikey's

Really loved this game, I've been wanting to make a FNAF Game with GDevelop and I was wondering if I could get a copy of the source code, to get kind of an idea?

I have a problem, I don't know if it is a bug or its me, so when I hear the music at the right door, I close it, and wait for the music to stop, but I get jump scared, is it me or is it a bug,(plus, im on night 4, MacBook Air, and im not talking about the music box) Also great game, I love the style and the story, 10/10

Pretty surprised this game is underrated, has a lot of mechs that well, aren't really hard to learn. I'll probably make more videos of this game soon

Honestly i love this game so much and its really good. Its really underrated sadly. I think it would be cool to have a remake and possibly get to know more about the lore.

Please tell me how to deal with a green bird? I tried those keys that were shown before the beginning of the night, and none came up. Maybe I didn't understand something?
