I really enjoyed it. It was really creepy and unsettling to me. The choice of music also helped in giving me the chills. The story is good too, the idea of 'not knowing anything that's happening' is really scary.
I feel a main problem I had was trying to find objects, but perhaps that's just me (I had to use the tab trick most of the time).
All in all, I enjoyed it. I hope your aspirations of becoming a game designer are realized.
