Atmosphere was on point. I like how the game starts with the computer booting up noise.
I loved that the GUI was interactable and part of the game. It was also very clean.
All the sound effects were really awesome, too.
The splash art and logo scenes were top notch.
Gameplay wise, it was a little unclear as to how to progress, but then again, it's a puzzle game right? So I think it's fair game. It wasn't really that hard anyway, so it didn't take long for me to figure it out. I can see how it can progressively get harder and harder with obscure hacking methods appearing eventually.
I think it has a lot of potential. Looking forward to what you do in the future!
By the way, thanks for playing my game!
