Thanks for the feedback, it was my first attempt at a FNAF game, so I think I messed up the pacing way too much. There's a bit more going on with the last nights, but I agree that the first couple of nights feel like a severe drag to play. Heck, it's enough to bore me as well, hence why I haven't tried playing through the entire game after I tested it once.
I wasn't trying to make this too scary (since it is based on next-bots), though I probably could have done more with the project, and I agree with loads of the points you give in your video. I'll take them into consideration if I attempt to make a sequel to the game.
Thanks!
