Eh, I played it in the equivalent of lunatic, and the difficulty was pretty nice.
Then I played it in normal, and even the stage 2 boss managed to get me confused.
I like the challenge, I'm on the side that touhou should be harder (AKA th11 tier) than it actually is, but ZUN is too worried to please the fans, which is a put off.
As for the game, what fucks it up the most is the controls. The "get line" is higher than where it tells you, the speed is kinda shitty, and overall, the dev was kind enough to not let you pick up items by going all the way up because some nigger will spawn and kill you anyway, lol. Nice one.
Also the frame refresh is kinda bugged as well when there are a bunch of bullets on the screen. I don't know if Jinx ever worked in other game before, but I'm guessing this must be his first so it's understandable.
I figured that since this is the first game that it wouldn't be so as good as the others so don't worry; once I cleared this one I'll try the others. If anything, I didn't like the music that much compared to 2ho, but the difficulty really picked me up.
