The door with the flame

After a moment of hesitation you decide to try the door with the flame. The silver key fits perfectly and with a quiet click the door unlocks. With your sword at the ready you walk through it...

...and find yourself inside a very large and very warm circular room. There are flames of various sizes and colors moving around you, seemingly at random. The heat they radiate makes you sweaty in a matter of seconds.

“Oh, fuck!” You curse loudly as you realize something disturbing: You are in the exact center of the room, and there is no trace of the door you used to get here, so there's no way to go back.

With no other choice you start examining your surroundings. The first thing you notice is that the smaller flames move faster than the larger ones. The second is that there is no obvious difference between the different colors of flames, as least as far as you can see. The third is that the floor, walls and ceiling seem to all be made from gray stone. The floor is quite warm, but not too much, and you guess it must be the same with the walls and ceiling. Finally, with some effort due to the constantly-moving flames blocking your line of sight, you notice one last important detail: There are multiple closed doors leading out of this room (or at least you hope they are leading out of here).

Having finished your examination you switch your focus to what you should do next. There are two obvious possibilities: Dash between the flames and towards one of the doors, or try to slowly maneuver between the moving flames and reach one of the doors. The latter will be much slower but safer... probably. The former will be much faster, but with the flames moving seemingly at random it will be difficult to avoid them all.
