The biggest issue with Touhou 11 was that all the playable characters downright sucked. The only good bombs are Yukari's and Aya's, and they suck at damage and scoring respectively. Reimu B and Marisa C are so weak that even when underneath a boss the whole time, you're at risk of timing out. Marisa A requires you to shotgun while unfocused in order to get marginally higher damage than Reimu A, and we call this the "high-power type". Honestly, 80% of the perceived difficulty of Touhou 11 is probably from the playable characters. At least UFO's characters aren't nearly as terrible, and the bombs are back to being unique and powerful (MASTER SPARK).
Oh, come on, Touhou 11 is by far my favourite Touhou. I agree with Yukari, every character sucked, except for Reimu A which is the only character that's actually playable in that game. I can get as far as Stage 5 without continues, that is, if I have any luck dodging Satori's Border of Wave and Particle (which I successfully did today, yipee)
Also, the bullets aren't that hard to dodge ... I mean, the patterns are right infront of your face and half of the attacks just require some precise movement.
Oh, and my favourite song from T11 is Stage 4's main theme, Heartfelt Fancy (NOT NANCY)
(I fail to find a video with meowing in Heartfelt Fancy. Without it, the video just doesn't sound ... right. Then again, while searching, I did find this totally awesome remix)
