From start to the end game player experience sense of freedom and one puzzle focus. Movement of the astronaut is easy with full 3D view during the movement of after - to see safety ahead, or environment around - which is stunning. Each puzzle is sooner, or later very clear - if gamer pays attention to voice of astronaut, to entrapment situation, girl whos footsteps he is following... In case of extra need of help, YouTube Walkthrough is available, so not big deal. There is only one 1/2 bad point and it is auto-saving of the game. It actually saves only point of beginning of the buzzle solving process (or way to). So, if gamer leaves the game, return is not to the point when he/she was last time, but to beginning of the puzzle which was not finished. Also - for games which have been having option to save several stages of the game there is non of it here. Good news is that it is possible - you have to go to "C:\Users\\AppData\LocalLow\Stage 2 Studios" and copy "lpSave.txt" and save it elsewhere. When you later copy it back game will start on puzzle you have started when "lpSave.txt" was created.. :) not ideal, but it works, I admire creators of the puzzles created as this Game is , 3D environment with realistic objects and surfaced, it is pleasure to even start over and to look around for beauty missed out first, or second time...
