Thanks for the in-depth review! I'm glad you enjoyed the atmosphere of the game, that part is my favorite aspect of the game as well!
I also appreciate you telling me how your gameplay experience went, it helps a lot to see how your run in particular went. I do feel like the destroyable collectibles hindered many player's experiences (I like your use of the term "item hostage"), especially since the player has to frequently shift focus between dodging bullets and shooting enemies while avoiding shooting limited collectibles. The velocity definitely has to change as well, since it didn't fit well in a danmaku.
I appreciate that you were willing to play 40 minutes of my game, though! I'm glad you found the atmosphere interesting enough to keep you motivated. Have a great rest of the jam, gloriousclover!
