Great story and usage of the theme. The writing was excellent throughout and seeing Marisa change with age while Enoko remained the same helped to establish how much time was passing.
The visuals were great, making this one of the best-looking games of the jam I've played so far. Both the 2D visual novel sections and the 3D gameplay sections looked stunning and show an impressive amount of work given the short timeframe of the jam.
The gameplay I felt was the weakest part. It was repetitive and frustrating to me. Your hitbox was too large I felt, and it made actually dodging nearly impossible. The strategy for most enemy waves felt like just shooting the ones on one side and hugging the walls to go around the others. The amount of downtime between getting hit and restarting added to the frustration. Worst of all, I encountered a bug where choosing "try again" would go to a white screen and the game froze. This happened to me three times and contributed to me almost not finishing the game. I only got one ending because I didn't want to play through the game again and risk that freeze.
The sound was good, the stage music was engaging and didn't get tiring despite how long I was hearing it. The remix of Enoko's theme that plays in the cutscenes was also quite nice.
