Escape the labyrinth

This is a practice for a class called Game Development. I used the most basic asset called FPS microgame.

In this game, you have been trapped in a dark labyrinth, you should try to find the key, use it to open the portal and escape the labyrinth.

Enermy is generated with time, they are getting stronger and stronger.  

You can also find other resourses and items in the labyrinth. Hints are on the air.

try to find the destination !!!
