Ah, the controls, my old nemesis - we meet again.
My biggest struggle with this game were actually the controls. They're very responsive, but the key mapping kept throwing me off. I don't know why, but using WASD for movement and spacebar for jumping never clicks for me. And I really missed a key to progress the dialogue. Other than that, absolutely no complaints.
Such a fun game! Really polished. It's obvious that a lot of thought went into it. The puzzles are fun, the learning curve is nice. It never gets fiendishly difficult, but it's not mind-numbingly boring either. Having the mannequin is a clever mechanic and it's fun to play around with. I love that it's climbable. Graphics look great and the music is fitting. The story may not be something to write home about, but that's exactly what I want from this kind of game. It sets the mood perfectly without overstaying its welcome. Oh, and I was amused by the enemy you-know-where. :)
Overall, a really well-designed game. Fun!
