A pretty nifty game with a nice style and difficulty curve to it. Wasn't sure how well I'd deal with the controls after reading the description, but you've done it quite nicely!

Was quite fun to leave a small trail of destruction, even if I only could last about 100 seconds before my brain gave up from Too Much Happening. Nice work! :D
Also, here's a bad fan art:
