PARENTS have been warned not to let their kids use a “suicide” dating app because it is too dangerous to play.

Doki Doki Literature Club is going “viral” in the UK but it has been linked to the death of two teenagers because it features dark themes of self-harming and suicide.

The controversial game is easy to download and begins with the user playing a school pupil who wants to write poetry to impress girls.

But it quickly descends into a shocking psychological horror and parents are becoming concerned because more children are playing it on their smartphones.

Callington Community College in Cornwall has even sent a letter to parents warning them about the game.

Assistant Principal Paula Mathieson wrote the letter and wanted to ask parents to check that their children aren’t using the app.

She said: “There is a new app that is going viral among many primary and secondary school age pupils.

“The app is called DOKI DOKI (literature club). The game is advertised as a school dating app and does not require parental checks to download.

“The app begins as a colourful and light-hearted game but takes a sinister turn within an hour of children playing.

“Their online friend starts to talk about depression and eventually commits suicide.

“Please could I kindly ask all parents and carers to check that your children do not have this app installed because of the associated dangers.”

The anime-style video game has been downloaded between two and five million times since it was released in September 2017.

It has been linked to the death of 15-year-old Ben Walmsley from Bury, Greater Manchester, whose father said the game “dragged” his son in with its “dark” themes.

He died in February this year and despite there being no evidence which proves the game was linked, Ben’s dad Darren has blamed the app for contributing to his son’s death.

After Ben’s dad spoke out about his son’s death another parent, Mihaela Portz, from Croatia, said the game may have played a role in the death of her 12-year-old son Rok.

She told The Sun Online: “He was playing the game in December, and a girl in his drama class also liked it.

“He wanted to get a present for her so he made a Doki Doki t-shirt.

"I did not realise the nature of the game because at the beginning everything is so cheerful and there's nothing strange or dark about it.

"He told me that the game starts to be weird and little bit scary, but it was not until his death that we found the real nature of it."

Two months later Rok had taken his own life.

Cops have also issued a warning about the game and described it as being a “risk” to young people.
