When I was a child, I went through a Digimon phase. One night me my brother were outside jumping on a trampoline or something and we saw some little floating lights swirling around us. There seemed to be more and more of them and I got terrified cause I thought I was getting sent to the Digimon realm or something, so he and I ran away screaming. So that was my first experience with fireflies.
I was like 4 or 5 and I was basically spooked every time they gave you a timer. Which once I found out that the whole game was timed got me proper spooked. At least that’s what my mom tells me, I don’t actually remember it that well. I remember the colour-fill-tool ghosts being a little spooky, I remember there being a scene where you have to play a xylophone (?) that was also spooky. OH and the ticking clock sound that gets louder when you’re in certain parts of the house.
Oh yeah, the clock sound was probably the most spooky part. I still find Deadlines scary today.
