Well presented! I enjoyed the aesthetics and how the main character looks. Gameplay wise - some parts of it made me feel a bit mixed, unfortunately:
- The shot sounds felt way too loud and distracting, which forced me to take off my headphones. Thus sadly I couldn't hear the soundtrack at all
- The boss only ever used a single attack pattern, which was fairly trivial to evade. If it had some more attack variety, or maybe some small backup enemies arriving as the fight goes on then it would have been more engaging for me. I also imagine some kind of bullet hoops to fly through, I think that could utilize the plane flight mechanic nicely
- Not sure how the theme was implemented? Themes are optional so it didn't affect my other ratings, but still wanted to mention it
I think with some more work put into the gameplay aspect, the game could be a pretty fun experience ^^ You already have a solid visual foundation. Congrats on finishing the jam!
