A lot of stuff from Comiket don't really care about copyright. Probably just some nutjob.
I find Genetics and the second "heart" card (the reverse of the first one) to be the hardest of Koishi's. 2nd survival is pretty hard to capture but very easy to bomb through. + it's completely static.
i really need to take some time and go through all the reitaisai stuff. ugh, why do i have so many things to do!
You know, it's really odd when old people do Touhou stuff, but that's just awesome.
