Very creative, the writing on the VN portion was nice and the presentation of the bullet hell sections, especially the bullets smoothness was a delight. A personal note is that I really like the VN backgrounds, looks like a mix of early 2000's to early 2010's VNs, where one had really blurry real life backgrounds, and the other had so polished drawings that they looked like pictures. Only complaint was a bug where I skipped the second date by pressing the bomb in the first stage, the text appeared in the middle of the action.
Incredible work nonetheless!
