Thank you for taking the time to give us some feedback, and I'm glad you enjoyed the game. If we decide to continue working on the project, we'll definitely try to address the problem with the controls and destroying ships too quickly. In the meantime, if you'd like to hear the full music with all the instruments, our excellent composer posted it on Youtube here.
I'm a huge fan of rhythm games so I'll make sure to check out your submission as well. :) I'm looking forward to it.
