OK, I gave DDC a fair chance, and I'm disappointed. Between inane life/bomb fragment system, TWO shottypes that just outright break the game (MarisaB and SakuyaA), patterns that rely on badly-executed gimmicks (screenflip and hitbox screwup aren't the worst here actually, the real problem is with bullets that appear/become distinguishable too close with too little time to read them, as well as horrible slow/fast bullet combination usage) and uninspired pattern design (Sukuna would pass off as a stage 5 boss, but feels too lame for a final one), I just can't like the game. Of course, it's not all bad and has some nice things, but bad ones outweight them by far for me. I thought I just needed to give it some time, but no, it felt like a bad fangame from the start, it still doesn't feel like a good Touhou game now.
This pretty much means I'm no longer interested in further Touhou games. I like most previous ones and think they're pretty good, but with this one even I have started questioning ZUN's creativity. So much that I have little hope he will do anything good in the future. Of course, I like new characters, stories and music he makes, but not the gameplay. Oh well. Not that I'm too sad, I have enough catching up to do with just what I have already.
In short, I am a total nineball for worrying so much about this piece of a game for so long.
