Well, some people who've NEVER played a scary game in their life they might think it's scary, but I don't think it's scary. If you want to know how my experience went...well...all I'll say is I kinda got a little sad at the ending of act 1...
Well, it seemed like a normal visual novel that had typical anime stuff happening right? Examples of those things would be:
A tsundere, A typical male protagonist, girls with large breasts, Odd colored hair, a childhood friend, and most importantly: where the heck is the parents?! Well...this might be true...but the game took some VERY dark turns....but before I talk about the darkness of the game let me explain how the typical anime cliches work with DDLC:
A tsundere: Well. Natsuki is a tsundere but it would only show if you called her cute or something although her tsundere self also showed when MC said how good Natsuki's cupcakes were.
Typical Male Protag: you know EXACTLY who I'm talking about, the boy you play as in the game aka MC.
Odd colored hair: well..yeah obviously weird colored hair is a thing in anime and well you can VISIBLY see how this applies to DDLC... *Cough* Sayori, Yuri and Natsuki *Cough*
Girls with large breasts: Well... I say girls but the one that this applies to is Yuri.
Childhood friend: Yup...the classic childhood friend thing...this obviously applies to Sayori. Where the heck are the parents?: Yup...everyone always asks this question when they watch an anime...but the thing is the only parent in DDLC that's mentioned is Natsuki's dad...but what about the other girl's parents and MC's parents? What happened to the parents!?
SPOILER ALERT: DON'T READ ON IF YOU DON'T WANT SPOILERS
Now time to get into the darkness of DDLC:
Basically, it seems cute and innocent at first but ending of act 1 and starting at 2 is when you finally figure out that it ain't a cute and innocent visual novel, but find out that it's a dark and (possibly) scary one. The dark parts are things such as self-harm, suicide, depression, and all that kind of stuff. Obviously, some people may be sensitive to seeing these types of things which is why the game gives you a warning in the start it basically says that you shouldn't play DDLC if you're under 13 or easily disturbed. Here's one of the darker things that happened in the game: So...Sayori or Yuri confesses to you right? Well...no matter which way you go they'll still die, Monika even explains why Sayori had blood on her hands when she was hanging...she said it was because Sayori tried to save herself at the last few minutes...but failed and just ended up choking to death or something like that...apparently she wasn't high enough where she'd die quicker so instead her death was slow and painful...
