Fine and a well made game, although gets some time to get used to it.
I like that it's using both a command interface and GUI at the same place.
Could see this game be developed further, although I had a bit of difficulties trying to solve most of the missions. I like that last mission being that you have to input a key. Downside about this game as it requires to type full words as compared to actual commands being truncated words formed in least space possible.
Fortunately, it wasn't much of a hassle to type that much anyhow...
Oh and I got that suicide malware or virus, ain't nice and this primitive operating environment or system has no anti-virus program *AHEM* if I weren't to note to some achievement that can be done by having a PonziPal doing the work.
While simple at best via icons and other, albeit commands as I mentioned before, being somewhat too long to type. Then again, assuming by that BIOS shown or computer starting up, makes sense to have command-line interpreter to have longer commands by being from, assuming being in 2000 or later.
Missions, itself are put together modestly, not much to overwhelm with every new feature.
I have this feeling I just could terminate the connection between those suspicious peers, yet I either mess up or not succeed.
There are quirks but it's mostly fine, just that as long you focus on what are you terminating before you decrypt another connection.
In the nutshell: Short bittersweet game, while nerds can enjoy the hell out of this somewhat boring game, it does give some intense feel to it. Commands are somewhat long but as long you're up to speed, it's all fine and might as well be dandy if lucky on few of the missions available on the game.
Four stars.
