If you only had time to download and play 1 game this year, 100² Logic Games-More puzzles  by Andrea Sabbatini  would probably be it. There are 50 new games and each one has 200 levels.
I really like the game called Planets (see first image.) Each row and column must have a sun and also a cloud to block the sun.  Of those 200 levels, I've solved about 75. 

However: at least 10 levels of this game had multiple solutions. But the program only recognizes one.
This game is a nice variation on Akari from 2012.

Andrea: fantastic job!
