I'm the creator of QTE Champ on XBLIG. I was googling around to see what the general feedback was and found my way here (I've visited the site plenty of times, just never the forums). The first thing I want to do is thank you for finding my game and sharing it with everyone else. The second thing is to tell you that the gameplay video on YouTube that you linked to wasn't uploaded by me so I had no hand in deleting any comments and I'm sorry yours was deleted. I support whatever people have to say about the game positive or negative because all thoughtful feedback is equally valid in my book.
Okay, with that said, let me give a quick blurb about why QTE Champ exists. The game is very obviously Shenmue's QTE Excite 2 arcade game -- and that's exactly what was intended! Back when I had my Dreamcast, I was addicted to both the QTE games in the arcade and for the longest time I wished there was a stand-alone version so that I could play them without starting Shenmue, walking to the arcade, and spending my in-game money. After years of wanting it, I finally just went ahead and made it myself. My hope was that this would bring other fans of the original mini-game like me out from hiding :-)
Every comment that I've seen on the YouTube video so far seems pretty positive and it makes me happy that the game clicked with the intended audience. Also, don't worry about purchasing the full game because I'm going to give you a download code for it. Just PM me so that I at least know this post was seen and read and I'll sent it to you. I also added you on Xbox Live.
Again, thanks for sharing the game with everyone. If you all have any questions let me know.
Edit: Went back and fixed tyops and grammar mistakes -- I originally wrote this post on a tablet.
