That wouldn‘t work because you could still replace the blocks really quickly while being out of reach. But it would make it certainly much harder to get those long times. Maybe you could also make the Platform smaller so you can‘t place blocks while being out of reach.
I found out how.

I think the Bloody aBedless and A70/A60 are the best drag clicking mice. The problem is, that they are not available anywhere(You can buy them on ebay for more than 150$). I personally use the roccat kain 102 because it is cheap.
