Stress free Touhou 1 where you can't die is nice. Pretty fun playthrough, even if attacking on the ball didnt always register.
Though I wish the boss had something to it other than just being stationary. Since you can't die, you could have it do stuff to protect itself like make a shield that changes its location everytime it gets hit. Also, a dash/slide kick function would've been nice.
For some reason, the portraits during dialogue were stretched weirdly, might want to get that fixed.
Also, some tips for unity, there is a function called application.targetframerate that locks the fps to the target frames, so you can lock it to 60. Also, try making the music player a singleton that persists through levels so that the music stays seamlessly through the levels. (use the dontdestroyonload function)
