The UI design of this is really nice but it was honestly a bit frustrating to play:

Very unintuitive start that unfortunately keeps ups: I don't know how you are supposed to know to search "Diagnosis" to properly begin - did I miss something in the files?  I had to have the walkthrough open the whole time just to know where to go next.

The password input feels weird as well: The first password Hidden in the notepad was good but every other one after that seemed to not register on the first attempt - I actually got all of the locked file passwords on my own but for whatever reason I was always told it was incorrect until I either restored the game or refreshed the tab - so I would constantly be checking the walkthrough for information I already had.

The Morse Code section was great, thankfully I was told from the get go to search the guide chart but again how liberal is the search terminology if that bit of information was not provided up front?

The pipe puzzle was a fun little section as well - no complaints about it: I might have just been stupid to not realise I was supposed to search the IP Address rather than using the command prompt.

The picture code puzzle was ok but the 1 looks more like a 7 to me which really tripped me up until yet again I checked the walkthrough to see if I was just going crazy - I naturally wanted to see if combining the windows a certain way was part of it but not really, could be a fun idea for the future?

Lastly the popup attack is the most annoying section mainly due to the length and lack of feedback - I wasn't sure if I was making any actual progress it was that long but I powered through it, would recommend shortening it just a little or provide an indication that you are progressing.

I appreciate you didn't have a lot of time to do the story but honestly it's good enough for me. It was short, simple and open to interpretation.

There's a promising game here if you keep at it - if this was a quick project for a jam then fair play but I did not have a good time playing.  I hope to see it improve in the future and I will come back to see at some point :)
