I think this was fun and has a lot of potential. The story was engaging and you did a good job giving little hints and encouraging exploration to try to learn more.
I found the SFX to be a little loud compared to the music. It's easy to adjust the volume individually, which I appreciated. It would have been nice if the screen with the Inventory, Save, Load, and Quit has the Options as well, so you didn't have to quit to get to it. The Options not being in English when the main game is did make the changing settings a little harder though.
Checking all the computers and emails did start to get a little monotonous, though it was rewarding to find new emails. Something I noticed was sometimes when I opened an email folder, there would be a back arrow, though it just exited you out of the computer all together, and other times it didn't have one. I think it would have been nice if, after reading an email it took you back to the email list on the computer. From there, it would have been nice to be able to either read the next email or go back to the main list to pick another folder, and from the main list have the option to exit the computer.
I found some issues with some of the collision shapes Locker Room. (I didn't actually figure out how to disarm the alarm, but I wanted to explore and see what happened if I tried going in anyway.) I could walk through a few of the lockers and through the showers and a few other spots along the walls into the blackness around the room. The security guard still spotted me in that area and resulted in a game over.
I had fun playing this one and hope you continue to work on and improve it.
