Very fun game overall, even though I wish the walking speed was a bit higher.
What I don't really get are the different ways to succeed, since the straightforward way is 3 times faster than the rest, and killing the generator basically means getting the guard suit.
Is there a bug or is the guard suit allowing the passage at the construction site normal?
After I killed the lights, I didn't know what to do other than just go the straightforward way again.
Overall, a really good game, but a bit less points with the adherence to the theme and originality, since the game is obviously heavily inspired by Hitman, and the "one bullet" doesn't really define the game in any way.
