Great entry!
The atmosphere was really good. I had like these Half Life wipes. Cool interactions. The Lockpicking is really cool, but felt a tiny bit clunky. I cant really pin it down. Maybe that I had to let go of space to turn the pick. And the Movement felt a little like skating. I think easing would add some weight.
But all in all the controls were really smooth and the interface was great. Never had a problem to understand what to do. Also the sequences were neat, like the barrier touch and the ending.
For you first game, its really awesome.
