Great atmosphere! I liked playing as a droid, and how the sound effects painted an image in my head what the character looked like. The first few puzzles were pretty good, though easy.
There didn't seem to be a way to orient the 4-way puzzle correctly, had to brute force it. There was a similar blue light above the hint as there was above the door, which like an obvious hint, but it was a red herring instead.
But that "enter password" puzzle... First of all, I don't think I would've found the hint without reading the description.
Second of all, I looked and found nothing it could refer to in-game. The most reasonable answer I could find by googling was "Greenpeace" and it didn't work. I did find the answer in the comments, but...
If you want to put passwords like that in your games, please make them only refer to something found in the game itself. There could have been a book about the subject, or a painting/picture.
Aside from that one puzzle, the game was great, and it would be interesting to see a longer version.
