This is a clearly a professional entry - it shows that four people were involved in producing it. The concept behind the adventure is interesting and it is well executed. I think the map should be larger as it is the key to the game and ideally you should be able to circle the numbers for the door episodes as an aide memoire. The formatting is too tight with not enough space between the episode numbers and the preceding paragraphs, nor between the illustrations and the text. Overall, it looks as though you've tried to squeeze a little too much into 4 pages - it would be fine if you spread it over 5 pages. As for the theme and narrative, I really liked the Tesseract itself but I just didn't buy the involvement of a Professor of Theoretical Physics - I studied physics myself at university, and found that such academics are not the adventurous type!
