I don't want to rate your game, I mean, it's a game due to it having a challenge and a victory status but... It's pretty much all it has. There is a lot of stuff there that doesn't work properly. Also please consider making folders and organize your assets, it will make things easier for you in the long run.
And please consider making a proper executable file. Just go to "Build settings..." and click "Build", save in a new folder, then zip the entire folder containing the .exe and the game_data folder. For extra fancyness, make a readme.txt
