This was fun! I enjoyed getting the upgrades and final boss was great! I loved the different attack patterns and it felt satisfying to beat. I also really liked the music.
If I could give one piece of feedback, it would be that the ranged weapon felt odd. I think it was mostly the controller mapping. Since you're using d-pad to move, it wasn't super intuitive to move your left thumb to the stick to aim. I felt like it probably would have been better on the right stick. Even better if it was on the right stick and all you had to do was aim it and then flick the stick back to shoot. However, I did like the slowdown while you were aiming. That was really helpful, especially when shooting the buttons through those narrow passageways.
Overall, great job! I enjoyed playing through it. Oh, also the portrait art and the mid-air attack animations were really cool.
