I don't think I've seen a FNAF clone in SBIG before, but this one wasn't that bad. And I say that as someone who was never a huge fan of the series.
The voiceover was funny, the characters coming to wake up the tortoise were funny, especially the still images moving around. I especially like how Tortelvis' image changes if you press the button for the room he's currently in repeatedly.
The little sound effects for every action in the game was a great touch, gave it some juice but in a SBIG way.
The gameplay itself was, well it was like FNAF basically, which I wasn't a huge fan of but don't have anything particularly against it either. It did switch it up a bit with the randomly placed buttons to shut up Percival which was nice.
it did have some very eerie atmosphere to it, especially the intruder. And I know there was no intentional jumpscares, but my god the sudden shouting of Percival or Tortelvis or text-to-speech made me jump a couple times lol.
I sadly didn't make it to the end, got caught between Ke'in and Percival at the same time and just got rinsed. From what I played though it was pretty decent.
Good work!
