Crime Scene Valentine edition vs. regular edition - can I delete one? Why have 2 aps?

I grabbed the valentine edition a while back and now I have two apps effectively doing the same thing. Which one should I abandon?

You can only access the special Valentine's Day case from the Valentine edition. If you have already completed that case, feel free to switch back to the regular edition if you need to make space on your device. If you are still working on the Valentine's Day case, you can temporarily uninstall the regular edition to make space.:)
