While it is purely cosmetic and I hope no one would rate your adventure less favourably as a result, I think the issue of the lack of space between the numbers could be easily fixed without it taking you over four pages.

All you would need to do is to move the section numbers to the side of the sections, rather than having them above them. That way the space previously occupied by the number would provide spacing.

As it is though, the tight layout is not having any negative impact on how easy it is to play the gamr.

Good sense of mystery, but I was unsure of what the end goal was that I was trying for. I guess visiting all the doors and windows? I just randomly wandered around without purpose and noticed there were a lot of chairs.

There was a little too much going on in the rules for me. I guarantee that I messed it up on several occasions.

After hitting time marker 20 things reset on me and I lost interest then stopped reading. Sorry. =(

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! 

The world dissolved, and I’m imprisoned in the tesseract forever. Will try again!
