Use arrow keys or WASD to move the character. To mark the front of the triangle, you may see a red dot which is supposed to represent the face. If you touch the black walls, you will get restarted to the orange part of the maze. Once you get to the blue part of the maze, for Level 1, click space. For level two, click C, for level three, click B.
Thanks to WonkaCodingFactory, for giving the idea. This is the first of the many series I plan to code. It's all easy so you shouldn't have a hard time. If you see any problems, tell me in the comments.
