I first played this game when it came out, a PC game which I bought in a double pack with Cannon Fodder. It's a sci-fi point and click adventure game.
I came back to play this the other week, as it's freeware now.
A lot of these old point and click adventures run on an engine called SCUMM, so now that engine has been remade and ported to a ton of different platforms under the name of SCUMMVM. It's really good, because you don't need to emulate an old operating system, this engine works as its own standalone machine for these games, making them far more portable than other older games.
You can get SCUMMVM and Beneath a Steel Sky here:

I couldn't remember very much at all about this game, so I had to refer to the manual to find out: if you want to access your items, move the pointer to the top of the screen.
It's a really good adventure. The script is very funny at times, gets far more serious near the end, and when it's infuruating it tends to be at the nature of the characters or whatever, rather than at obscurity of puzzles or game mechanics. There are a few points where it's hard to proceed because you simply haven't seen an object you should have picked up to use. There's a section near the end of the game where it's suddenly really really easy to die, as well. Apart from that, it's fairly straightforward.
The graphics are good, detailed, atmospheric and largely clear to see objects in. The sound... well, the voices are good, it's unusual to hear strong Northern English accents in a sci-fi game... the music really seems outdated and a bit annoying, though.
Overall, well worth my time playing. :)
