Thank you for your patient reply. Since you had offered the method, I eventually made it to the stage 7, yet I always cost more lifes than I predicted in 1~6, which cause my failure orz. Nonetheless, having a sight at the final stage is enough for me( unless there still exists ending, and my ability seemd to restrict me)
Besides, I'm surprised too when I got the reply when I comment on a jam game 4 years ago :p. Under a pressure of fast-paced life, I could hardly found time to play huge games, in stead of which I found touhou jam and determinded to play the whole series.( The embarassing thing is that till now I had only played 4/13 of them, from jam 2-5)
What's more, I'd like to submit a bug( maybe?) Between the stage 5 and 6, it's probably occur a error of a huge amount of danmaku, reducing my remaining life to 0( I tried to illustrate the photo yet the itch didn't reflect me at all, so I didn't even know could you see my awkward condition)
I know it's unrealistic to ask the author to revise a game published 4years ago, and I just want to warn this mistake to the person who may play it in the future.
ps: English is not my native language, and I might made several thoughtless mistake in the text above, hope they won't fluence my original opinion. If you found some offensive words, the only thing I could promise is that I didn't type them on purpose, and in that case I would apology for my inconsideration.
