Hi. I liked your game.
The graphics were pretty and the music fits the game perfectly. It gave me a "little nightmares" kind of feeling.
The first time I played it, I got stuck because I thought getting the white items was optional. I didn't get one at the beginning and when I was going down, the black could didn't let pass through. Was that supposed to happen? If so, maybe the could have been some kind of sign to let me know "these items are indeed important".
Other than that, the game was fun. Controls were responsive, maybe the speed of the player could have been a little bit faster, because it was a little too slow (for my taste) to move around and climb a ladder, for example.
Anyway, great job! I hope you are very proud of your game :)
