Very cool storytelling game. I like the show don't tell aspect of it. It encourages the player to explore the environment and unlock bits and pieces of the story. I think I got the general gist of the story - the coughing dude is dying, and he stole the Uplink technology to upload himself into the computer only for it to shut down anyways, right? If so, that's pretty dang dark.
As for the gameplay itself, a cursor would've been useful so I could tell what I was pointing at. I also think the windows being platforms should be made more obvious, it took me a while to get that I could jump on them.
Overall, very cool and unique experience. I enjoyed playing through it!
