Awesome comment, thank you! Yeah the music was supposed to be humorously contrasting to the shootin' part, but that may be a bit hard to catch.
Good point about where the player faces, in fact haha I can't believe I didn't think of that. I'll change it so that the player character faces the cursor position! :)
And yeah the frequency thing escalating so insanely was really just me not having time to balance things properly.
And ooh interesting, the stuck flying creature sounds like another bug that I've had happen, thanks for letting me know about that.
Regarding the non-textured area and the lag and the tactic of just running to the side, very sadly I just didn't have time to implement a proper play area. I guess I did some bad prioritization, oops!
Thanks again for the detailed feedback, much much appreaciated.
