Left and right arrow keys to move, and z key to jump. So far, there are two possible endings and one easter egg. The endings are super easy to get to and it shouldn't challenge you that much. Also, note that this is a demo, and that more content will come soon.
Thank you to the creator of Sonic.exe Nightmare Beginning for the music, and Idea to create the game on scratch. Also, thank you for playing and/or letting me be part of the scratch community. :). Hope you have fun, and comment some suggestions for me to take under consideration! If sonic.exe shows up at the start of the game, click the flag again.
