After almost a year, I finally shared a project! Please comment if you run into any glitches, and feel free to comment your maze code! Press the flag (maybe twice), and wait for my (amazing :P) logo, and the fading thing at the introduction. Then, press "create" to create a maze or "decode" if you have the code for a maze and you want to play it. To use the maze editor, just click the block in the top-left corner and drag it to your desired location (not in the editor). Then, if you wish, use the arrow keys to change its direction. **PRESS THE SPACE BAR WHEN YOU ARE DONE WITH A BLOCK** You can also drag the character to test sizes, etc., or just to see where it will start. When you're ready, drag the coin to wherever you want - the maze's goal will be to get to this coin. You can use the "help" button to see these instructions in the project, the "test" button to test your maze (use the arrow keys to move the character), and the "done" button for it to generate your code (be patient; if you have a lot of blocks this will take a while). If you have a code for a maze, and want to use it, just press the "decode" button at the main menu, and paste the code into the ask bar. Then, wait a few seconds for it to process, and then use the arrow keys to move the character to the gold coin without crashing into walls.
Thanks to @griffpatch for the coin, Public Domain Pictures for the maze blocks, and pixabay.com for the maze background at the main menu and thumbnail. Thanks to @durpdadur for the music, which you can mute by pressing "m", make louder by pressing "w", and make quieter by pressing "s:.
