Video Memory Game Timelapse

I made a time lapse of me creating a CMD game.

Concept:
1. 16 random blocks get generated
2. They disappear
3. All of them return but one is different
4. You must click the one that is different

Actual time: 32 minutes



This is the exact same thing as the puzzle in The Hidden City quest

 

You are still using gold blocks as a tribute to me :D

Anyways, nice video. Here are my tips:
I like to fill with redstone blocks an area between 2 rows of command blocks, to execute them in the order I want - and all in 1 tick. It's much faster than what you are doing with the repeaters. It's the best way to make your command blocks work fast and keep them organized (If you don't understand what I'm talking about I can show you on build).
Also, the long repeaters delay is aids. You should use some kind of a clock counter thingy instead. It's also much more elegant.

 

I've been using gold blocks ever since you told me :D

I actually did notice I could have made it faster but I only noticed after recording. I didn't really want to redo it all so I kind of left it like that. Next time I'll do it like that.
