The level clear song is a banger. I also thought it was really awesome how you represented the controller being connected/added. I was not expecting that, and it was a really nice bit of polish. The overall presentation of the game felt very finished, and the sound design came through really well. The player bullets were actually pleasing to hear, and the little needle guys sounded hilarious. The backgrounds were detailed and colorful, but they never conflicted with what was happening on screen; really impressive for such a busy art style.
All the levels were great. The second one, particularly, had some really cool stuff going on, especially with the color changes in the background. The boss fights were also super engaging. The visuals were spot on for the art style, but the bullets themselves looked good too. The upgraded weapon pattern you get later in the 2nd level was especially nice to look at. Really impressive work from the team. The whole thing is full of personality and polish.
