-Cutin graphic makes the gay man in me cringe
-Spellcard Names: Capitals!
-Blade Sign - Shattering blown glass knives -> Shatter "Blades of Glass"
Addendum to above: If you want to make the spellcard names appear "ZUN-style" try this:
"Shatter" \" "Blades of Glass"
In your spellcard names.
-Health bar isn't conforming or draining at all, makes it awkward
-Nice choice of music.
-The second slowdown made Danmakufu lock down for some 30 seconds, so I just minimized and browsed for a minute or two and then brought the window back up to resume.
-Background vanishing on your Nonspells, unsure if that's intentional or not.
-Lol 2nd (3rd?) to last Eternal Meek. Circle around~
-Some people might get ticked that all of your Nonspells are pretty much Eternal Meeks, but I absolutely love them myself. :*
I ended up finishing with a, uh. 5(6?)cc. Not bad. I can't figure out how to dodge a lot of it! But I have to say, as far as design is concerned, you did a nice job, didn't put in anything overly bright or annoying or gimmicky. Just straightforward Danmaku, and despite all my deaths it was enjoyable.
