I beat each level by finding all required items and getting out in time, but I never saw the option to enter Relax mode to take my time in order to solve the map puzzles. Is that mode only available in the full version? Great game btw!

failing on the first try because I don't have the dexterity for a maze puzzle kinda sucked. Are there a lot of puzzles like that?

Is this is just rinse and repeat for infinity and you are left to your own interpretations to objects you found or is there a campaign to it???

Will the full game allow you to invert the mouse Y-axis?
