You can only use this project once

THIS IS A PROJECT YOU CAN ONLY USE ONCE... (unless you find the block that definitely does not unlock the project so you can use it again)

Use WASD to move

You will likely see a warning that says "Please enable Javascript Extensions in the project editor settings to play." Here's some more specific instructions for doing that:

1. Click "see code"
2. Next to the name of the project (at the top of the screen), click the gear icon.
3. Click "Javascript Extensions" to enable it.
4. Click the green flag and play the project like normal!

Special thanks to @silver-rush for the code that makes the moving thing move
