I loved the idea of playing a Unity test! I feel sorry for the main character, he only wanted to be free =(
At the end, this game was almost a horror tale, the music were very unsettling.
The only thing I would point out is the character speed when they are talking. There were a lot of times that I tried to jump platforms in vain because of that, it was a little annoying. But I really liked the gameplay and story!
Keep up the good work ^^
