I answered Karakasa Surprise Flash in the previous thread, but - surprise! - just after I posted it, I devised a strategy to keep it somewhat sane and manageable with 3 captures and counting.
I suppose Lighty Falling Large Raindrops would be my replacement pick because it and its stupid hitboxes are not fun whatsoever.
Maze of Love is another one I'd like to add, but it's not so much a stupid spellcard as it is a I-suck-at-this-sort-of-movement. I feel this one is not going to last long, though.
I also skipped over the "most changed game" question because I didn't think much about it at the time, but IN and EoSD have certainly risen in my eyes. IN wasn't as good as PCB to me and had a lot of unnecessary stuff in it, and no visible hitbox turned me off for EoSD.
Contrary to that, PCB and especially MoF have fallen the most. The former has lost its magic as my first Touhou game, although borders and stuff are still pretty neat. MoF is still a good game, but it isn't very exciting and pretty much a worse SA with prettier backgrounds. I admittedly haven't played it seriously in quite a long while, though. Once again, however, they are all good games in their own right!
PCB is still better than IN. :V
