I had a lot of fun playing this game! it's thrilling but also relaxing at some point. It has such an interesting story that makes me curious about what will happen next. I'm a huge fan for the art style, It's simple yet so colorful, iconic, and magnificent. I truly admire how much the developers throw attention to the details in visual aspects, such as the animation, background, and character designs. Last but not least, the BGM suited each stage's atmosphere very well.
However, I think there's a few things that can be improved. Like the overlapping picture on the second prologue, causing Stella's upper body part missing (kinda creepy ngl). Also, as a beginner I found a few difficulties with the control, there's too many buttons to press and it took me a while to get used to it. I hope that can be simplified (if it makes any sense). Adding a check point system also might help this game to be more efficient.
Keep up the great work and good luck for the game developers!
p.s: I think Mr. Jasson make the BGM for the battle arena scene (prologue 1 & 3), I'm not quite sure though TvT
