Every aspect of this game is fantastic, and not just in the context of a game jam. I only wish we had gotten to see the Seiga furby in the end. My score was 261079, in case anyone wants to compete.
It's a known difficulty to implement melee attacks well in shmups, but I think this game did a good job. The first kind of enemy you encounter (aimed single bullets at regular intervals) was a bit tricky to approach melee range against, but it was fine after I got used to the range of Tenshi's sword. I ended up using Tenshi for most of the first half of the boss fight, and it felt like a reasonable risk-vs-reward to go into melee range for more damage.
A minor complaint is that perhaps a too large part of the score is gained on the last boss attack. Perhaps it should also be possible to maintain a combo throughout the entire stage? It looked like there was a section without enemies were the player has to drop their combo. Is this good or bad design? I don't know, but perhaps something to think about.
Thank you so much for making this, I had a lot of fun playing it.
