About me
Hi, I’m Louisa Heyen. Even as a child, I loved painting, writing stories and creating my own DIY projects.
After studying business administration and completing an internship in controlling, I first had the idea of selling Excel templates on Etsy. More and more product ideas followed — including a crime case file with its own website.
Because I had no experience with web design at the time, I actually built the first version in Excel. Step by step, I taught myself the technical side. On October 30, 2025 — one day before Halloween — the first Planique Crimes case was released.
You do not just solve the case. You experience it.
Planique Crimes combines a strong story, active investigation and cinematic elements into one connected experience.
You stay yourself
There is no assigned character. You are drawn into the investigation as yourself.
The story matters
The goal is not only to find the killer, but to uncover what happened and why.
It feels cinematic
News reports, calls and reveal videos make the case feel more like a film you are part of.
Thank you for being part of it.
Planique Crimes is an independent passion project filled with time, creativity and attention to detail. Every purchase, every review and every person who plays one of my cases helps this project continue to grow.
Thank you for discovering my stories and supporting Planique Crimes.♥
