Cool game! I like the different attacks that the beetle has, the bullet pattern is cool. I also like the pixel art is well done, the vines around the boss bar were a nice touch! If you decide to add anything or update it, I think making the crosshair a little bigger or easier to see would be good as its hard to see in your peripheral as you're dodging bullets. Could just be a skill issue though lol. I'm making a sorta similar bullet hell boss rush game, so if you would like to check it out and leave some feedback I'd really appreciate it!
