Hello Sakis Laspas!
I felt that the look and feel of the game was awesome! I personally thought the school (hallway and classrooms) were done very well. I managed to get lost finding the door in the maze, because it actually blended in very well haha. The only other area that had me stuck for a moment is at the end, it took a long time to prompt the ending (unless that is intentional). Retro mode was a neat touch too! Made a small vid.
