The story was interesting and made me want to learn more. I liked how you gave clues and hints through the game to help try to figure things out. I felt some of the puzzles were fairly intuitive, though I got stuck on trying to figure out the computer password by reading the books in the room.
Typing passwords onto the computers was a little clunky, particularly if you made a mistake and had to erase anything. It took me a bit to realize I needed to hit "ESC" to delete letters and even longer to think of using the right mouse button for mouse only play. I think it would have made a lot more sense if there had been a delete or back space button to click.
I also had some issues with the collision shapes. There were times I could walk through things that looked like they should have stopped me, such as some of the walls next to doors and some of the plants. Other times I stopped even though it looked like the space was clear.
I hope you continue working on this; I would enjoy seeing where the story is headed.
