My only problem is that ZUN used an odd resolution selection.
Which also leads to some graphics inconsistencies, like high-res character portraits among pixel-stretched sprites.
I think it's also part of why the game lags sometimes - ZUN hasn't quite optimized some of the computer-generated effects being rendered to large bitmaps, so there's some parts where DDC hogs resources. I get a 30 FPS drop when pausing after pichuun.
But these are pretty inconsequential issues.
Regardless, this game far exceeded my expectations, DDC is my no.1 Touhou now.
It's risen to my top 3 main series Touhous, among IN and UFO. I hope more people will warm up to DDC once it gets more of a foothold in the fandom and the official print works/spinoffs. The main mechanic ties well to the gameplay and the atmosphere makes it feel like ZUN's own "Alice in Wonderland".
Shanghai Alice, that is.gg ZUN I forgive you for TD
