The reason why it didn't work out the way I hoped is because of one comment from @AGameZ69 saying this: "Then there's the phone call voice actor... It's bad. Not trying to be a mean person here but it actually sucks."

So, even though development on Springlock II will resume as usual-and @PolskiAlan89 will continue working on this game with me, in terms of voice acting-, I will let you know now that I'll be back to voice the phone guide in another FNAF Fan-Game i'm working on, as soon as the full version of Springlock II comes out.

So, in the meantime, enjoy the demo, regardless.
