Idea Song/ Parkour Game Idea

I don't know if this is an idea people would be interested in, or if it fits in with the McParty idea. But it's about guessing the names of songs. maybe have it within a parkour map of some sort? Don't know how much of a detail I have yet on this. But post what you guys think about this idea.

Idea: So some lyrics of a song would pop up in chat maybe in a really noticeable color? possibly blue or red. After the lyrics would pop up. The first person to guess the song and writer would get so many points. Then the second player would get less. And the third player to guess it correctly would get the remaining points. (just like how the point system is based now) if only the song is guessed then they only get a fraction of points. same as with only guessing the writer.
To prevent people stealing answers: When the player correctly guesses the chat would say "(players name) correctly guessed the song" or "(players name) correctly guessed the song" or even "congratulations (players name)
To prevent people from memorizing the order of songs: The song lyrics could be rotated to a different order each time. and the songs would change over a certain period of time.
The parkour idea: It would be a parkour course that would be impossible to solve, but maybe have a feature that you could get one or two extra points. Maybe some hidden chests with diamonds or emeralds (a reference to the diamond mining game) where emeralds would be two extra points and the diamonds would be one extra point. This could be beneficial for the players that couldn't answer as fast, so they at least get a couple points. Also, there could be a couple chests that are harder to reach, so these would be for the more skilled parkour players. Maybe this could be set up into a different course for each skill. Not too sure. (what do you guys think?) But those courses could maybe branch off. For this course, it'd possibly be in the sky or have a bed rock bottom and if people fall past a certain level or hit the bedrock then they would automatically be tped back to the start. (or even a check point spot that once you pass it, you would only get tped back to there instead of the start, just an idea, depending on what you guys think.
So this would fit into the McParty theme: the parkour course could feature mario party builds. possibly buildings from mario party, windmills? there are castles correct? (excuse my lack of knowledge, never had the funds to get the game myself, I've only watched it played a few times on youtube, and maybe played once or twice at a friends house). But the builds. Use a lot of colorful blocks (that much I know about party; It's colorful), and have certain references to mario party.

Lastly: Does this idea seem okay? Does it need more thought/ details put into it? Or is this a totally bad idea for a game? Post your comments/questions/concerns/extra ideas, down below.
PS this is my first idea for a game. Did I do a good job?

 

thanks for the feed back, I'll make sure to keep this in mind. If/when I make another idea.

Same to you Signatured, thanks for the feedback, I'll definitely keep those in mind.

 

Now that I look back on it, yes I get exactly what you guys are saying. I'll make sure to keep all of these things in to account when making another game idea.
