DANGEROUS GLOOM

In this old mysterious castle (or dungeon), everything is plunged into darkness. Only some areas, dimly flicker with yellow-orange flashes, reflecting the light of torches. The darkness has a deadly effect on your hero, and every second spent in the darkness takes away his strength. However, when you exit it into the light, your strength is quickly restored, and this is the main thing that should be taken into account here.

The authors of the game do not provide a detailed description of the main character's mission, we will consider the game as a quest. When passing the first level, it is clear that the hero must take the key, running for a second into this terrible darkness, and then go through the exit door and get out. But what's next — go yourself.
