Well...
I know you were going after the whole "Where am i? I need to escape!" theme, but introducing yourself as the creator of the game seemed a little... bland? Making the key and the red block void objects seemed a little pointless also, since it doesn't contribute to the story or progression. When i saw the word "escape" I immediately tried hitting the key, which ended the game and also made me laugh. Not bad for a first attempt, but the title sort of implied some heavy metaphorical background. Keep trying, and surely you'll get it right!
Practice makes perfect.
