What a satisfying experience from every angle. The writing ties into some serious lore but Yuuka's teasing nature keeps it humorous throughout. The game has the bleak atmosphere of Dark Souls but big fancy bullet patterns covering the sky to delight the eyes. The boss music gets the adrenaline pumping. And the core gameplay of Yuuka crushing everything is just fun. Flight is hilariously overpowered compared to a dodge roll, but that fits the series perfectly. There actually needs to be more difficulty to match the Dark Souls inspiration. The game is rough at the edges, but that is what the expanded project is for isn't it?
Edit: Oh, and pushing is even better than flying, apparently.
