I'd thought about making my game lag by running downloads and programs while
playing, I'm glad to see that I'm not the only one who thought about it (cause
this idea sounds a bit crazy lol) Unfortunately, it didn't work for me.

I found a very useful tip on the internet, and I guess not everyone has noticed
it in level 1:

INSTEAD OF CLICKING THE PIECES ONE BY ONE AND DOUBLE CLICKING THE LAST, CLICK
THE FIRST PIECE AND HOLD THE CLICK DRAGGING THE CURSOR ON ALL PIECES YOU WANT
TO MAKE A CHAIN WITH, THEN CLICK THE LAST PIECE OF THE CHAIN, YOU'LL MAKE CHAINS
A LOT FASTER;)
