Hello! Thanks for the critique!
Yeah, I'm no sound designer (and definitely less of a musician, I'm glad you like it, but I really hate my music haha!), so I understand the complaints. Having options to configure screen-shake and controls is always a good idea, but I wanted to have a release date and commit to it, so... I had in mind one or two more enemy types, also, but I felt that would have taken me too long.
Thank you for playing again! <3 <3
