Update: A winner has been found! This challenge is now over. Thanks to all who tried!
I don't think anyone has beat the game yet... So, I propose a challenge:
To promote the game I would like offer a challenge and a prize for whoever can record themselves beating the game.
If you're interested, the first person to submit to this Reddit thread or to my twitter @boredmob their own YouTube recording of successfully beating EACH successive level up to the credits, I will gift the winner whatever Steam game(s) he/she wants up to a total value of US $100. You do not have to beat the 'City' level, you do not have to beat the bonus levels after the credits either.
That could be an interesting gamble if you're up for it. Watching this will be entertaining for me but it might be torture for you. :)
How I will contact the winner: I will send a private message to the YouTube channel you posted the video on. You can expect the message to come from this YouTube channel.
Anyway if you've read this far, thanks for checking it out! I hope at least a few of you will accept the challenge :)
