The minimalist graphics are very stylishly decorated and also generous with optical illusions that pave the solutions here and there, and done animations. The quiet, mystical ambient music, the soundtrack to the Riven - Sequel to Myst recalls and matching sound effects round out the audio-visual experience.
For me, Monument Valley belongs next to The Room 1 & 2 and Machinarium to the currently best Android Adventures / Escape Games. The absolute highlight was Level 8 "The Box", with its surprisingly quirky ideas for me.
Update 14:12:14 Finally there with The Forgotten Shores update that 8 new Level donated that an entire corner are partly heavier than the 10 level of the main game. Highlight is Level 7 "The Dungeon", which for me is the most beautiful and most original level of the entire game (liked even better than "The box" to me).
Although The Forgotten Shores costs 1.79 EUR but I think whoever does a good job, this must be paid also. And what else you get everything for 1.79 EUR? In the ice cream 2 scoops of ice cream in the pub a 0.3L glass of beer or cola, etc.
I do not regret one second buying the game and the update because Monument Valley is highly recommended for Knobel- and puzzle fans.
However Kudos are also due also to developers of ustwo, for a really well thought out and motivating Escape Game.
