I like the somewhat space-age solitude type world this is set in. 

I must admit though I personally didn't quite get all the puzzles. I got the telescope and floor puzzle and the code for the cabinet as a result. However, I didn't quite get the key box puzzle, although it let me grab the key without figuring it out. Unfortunatley the 'red pair' puzzle is a little beyond me and the time I have to invest in figuring it out. 

One thing I did notice though is the UI cursor is white, and the boxes on a lot of things are white or bright also. This causes issues with misclicks etc. Also, a sensitivity option for the mouse would be muchly appreciated. It takes a little of getting used to but there's no reason for the mouse to be so twitchy.

Overall though I like the concept. Given I want to branch into puzzle games there's some little pointers I've noted from this one.
