## Oyun İçin Neden Gerekli

Oyundaki karakterimiz karşısındaki kişilerin adlarını biliyor ama bizim
mouseyi üstüne götürmemiz lazım, ctrl basıp direkt görebilmemiz bence
daha hoş olucaktır.
## Changelog
:cl: Rengan
add: Basınca etrafımızdaki canlıların isimlerini görebilmemizi sağlayan
bir keybind eklendi, Varsayılan tuş: Ctrl
