Both of them sold quickly (both sold *eventually* last time). "Shinu ga yoi" actually has more to do w/ DDP than you would think. I hate to spoil the surprise, but IKD makes mention of it in the DOJ: BL interview.
I will write a report, but not post it for a while. I didn't get any video (camera fucked, and good ones out of town). I got some pictures, but nothing to masturbate over. I didn't get tickets to the talk event, but was knackered anyway. It was WAY fucking packed. At the other ones, when you finally got to the 5th floor, you were golden. This time, 5th floor you were golden showered. It was a 2 hour queue once you got up there. Such a fist fucking party.
Anyway, here's the details on the special versions. I'll include titles for oxtsu's glorious list.
TITLE: Guwange: Dai Cave Festival Tokubetsu Shiyou
-Little coin juicing thing when skull counter is gold doesn't require 1000 counter
-Was there a blue meter in the right hand corner before? There is now... and it did nothing apparently
-Bullets do far less damage
-Bullets that are turned pink w/ shikigami and go back to blue, instead will flash red & blue. If you cancel another one that was in the same group as that one, it will cancel and turn into a coin.
-Bombs give coins for all bullets on screen
-5th stage boss' Ape form sprite is scaled (2 to 3 times normal size)
-Last stage boss pattern altered. More balls... crazy fucking pattern, but far less bullets. One guy cleared it... another came very close. I had to leave.
Muchi Muchi Pork:
Dai Cave Festival Special Version
After defeating the boss of each stage, you got to fight a Pink Sweets boss.
For now, you can see a picture here:
DIE Cave Festival Special Version (die is not a typo)
At each stage select, you can select Level 1, 2, or 99. Level 99 features LOTS of suicide bullets from the get go, and bosses have much harder patterns. I got to the second stage. Scores were high. Highest for the day was 1.6 billion.
