As far as I can tell it is. But for the complete version of hacknet on steam (which is currently on sale) you could get it for $5, which is well worth it.
Very Very nice game! Even though it was short, it was quiet beautiful. Would definitely buy A more full version with a fuller story about the lives they lived.
I thought it was very good, the only thing that frustrated me was when I died several times by hitting the sides of spikes on the final level. Really cool game!
