This is a really nice take on the theme with all the elements (only scaled down for obvious reasons) one would expect from a cyber noir game - fog and a gray/dark setting.
The controls are working nicely and are very responsive, but the lack of "active" interaction is a bit like having an itch you can't scratch.
This game really have potential and I really hope you continue develop it (or have it as a basis for a complete game).
Really great job, especially given you only used four days to make it!
