This is a very fun strategy game, and the difficulty is quite fair and balanced. Also, if ads are a problem for you, turn on airplane mode. (Back to the game) The monsters are interesting and each one has a fun and unique ability. Why just three stars, then? The final-and only-boss, of course. The boss moves around invisibly and even if you upgrade your movement amount to its max, he has like ten more moves than you! Worse yet, hes entirely RANDOM! Into The Dim is a game about planning your moves based on the enemies placements, abilities, life count, move count, and your life and move count. So when you fight the final boss you never lean his move number, placement, and not even his life amount! Basically, youre running blindly seeing if you can run into him. While the game was comprised of puzzles testing the players skill, the developer(s) decided to go,"Yknow whatd be cool? If the boss fight was BS and relied entirely on luck! Yeah! Way to end a skill based game!" What Im trying to say is: the games levels and gameplay are fun, but the boss is BULL$#!~!!!
