Writing pseudo-code for assignment and want to double check if it makes sense

I'm a beginning CS student and would love for some help checking REALLY SIMPLY pseudo-code. Would you use a function? How would I write it?

Here is the problem:

Write an algorithm for playing a robotic version of the "treasure hunt" game. The game involves robots receiving clues that guide them to other clues until they eventually reach a "treasure".

Clues are represented by colors of tiles and each clue just requires the robot to move one tile in a direction (left, right, forward). After making a move, the robot re-examines the color of the tile it is standing on to figure out the next move, etc.

The rules for the tile colors are:

• White tile = next clue is the tile directly in front of the robot
• Blue tile = next clue is the tile to the robot's left
• Green tile = next clue is the tile to the robot's right
• Black tile = robot moves back TWO tiles then re-examines clues based on its new heading
• Yellow tile = treasure and game is over

The algorithm rules:

• The robot can only move forward, turn left, or turn right
• The robot is able to read the color of the tile it is standing on

Here is my pseudo-code:

     //assign movements and actions to variables

     whiteTile = step forward one space
     blueTile = turn left and step forward one space
     greenTile = turn right and step forward one space
     blackTile = step backwards two spaces without changing directions
     yellowTile = treasure found and game over
     tileColor = check color of tile 

     //initiate while loop to run continously until robot reaches yellow tile

     While tile under feet does not equal yellowTile
    // initiates the movements of the robot to start if loop
        Check color of tile
    // this if loop should run continously as long as tileColor isn’t yellow
        if tile color does not equal yellowTile
          output(tileColor)
          check color of tile


    // once robot is on top of yellow tile, it exits the while loop and game is over
     output “Game over, you win!”
