Very fun! The controls were a little awkward and made it difficult to play though. I suggest this. There's no reason to not continuously show the power meter. So with that in mind the controls can be simplified. Start with a 45 degree angle. Use left arrow or A to aim counter clockwise. Right arrow or D to aim clockwise. Up arrow or W to shoot. This will make for a much smoother experience. Start with 45 because that seems like a more useful angle and allows for one button press to keep playing.
