Wow, this is a lot of stories about embarrassing moment (new here on this site). This is the most embarrassing moment I had lately though I'm not sure this was posted already due to my inability to read through entire 33 pages

I recently started playing IN four days ago as Reimu without knowing the "time/final card" system, and after beating Wriggle on normal stage 1 with having >2500 time points, moved unknowingly into the middle of the screen thinking it was over only to collide to respawned Wriggle.
I got the bad ending later due to too many continues and was fighting Wriggle on the stage 1 again, and to my surprise found myself struggling against her attack, so I try to bomb to buy some time to recollect myself. Only that I didn't know I was facing her final spell card at that time, so when nothing happened I started pressing X button repeatedly in panic, losing my concentration as I turned my eyes to look at right side of the game to check if I had run out of the bombs, and getting bullet right in my face :/
Then I wiki'd IN and finally realized what was going on. Honestly, I still don't know most of the Touhou game's mechanics such as condition for getting 1 bonus life with BRAG BRAG BRAG BRAG effect sound and such (which by itself is another embarrassment

)
