Oh my gosh! This is a fantastic idea! I totally love it! You should definitely make a full game of this! I would definitely buy this game as long as it's reasonably priced.
Btw, do you think you could give me some feedback on my game? It's a puzzle platformer called Gravity Whipped. I have been working on it for almost 3 years now and would love to get some feedback on the demo.
Please let me know, and good luck :)
And I love your background too :)
