Thank you for playing the game!
As for the art, yes I did most of the art of of the objects and enemies. A friend of mine who's in the special thanks, provided me with the ship, the starry background and the planets!
Regarding the feedback, Yep I do agree I should've implemented a stronger indication for progress when damaging things. Though I wasn't sure if sound effects is the best choice in that regard, especially when everything that appears on screen is destructible.
As for the music, I agree with some quick-paced music
Thank you again for your feedback!
