Viability: The game is playable from start to end, with clear mechanics and well designed levels. The next iteration of a game like this would add clearer feedback for when you get hit, and at least a jumping animation. Other quick, simple fixes include choosing the option"orient to direction" in the enemy patrol script, to make the snakes turn around, and making a separate jumping box for the bottom for the character vs the rest of the body, to prevent the issue of sticky walls. Having said all of that, this accomplishes a lot with the time we had, so good job!
Presentation: Beautiful graphics, clean user interface, and hauntingly atmospheric soundtrack. It is impressive how far you both were able to create a sense of world building through art and mechanics. I just want to hang out here longer!
Theme: Very much in line with virtual world themes, for me this game is all about the excitement and apprehension of exploring virtual worlds. Having friendly npcs as collectables is an economic and effective way to create momentum, and the final scene serves as a visual reward.
Engagement: I had fun navigating the level design and exploring he world. I think this fulfills the assignment completely and then some. Yet, I hope you both consider going back to it and adding a few quality of life elements, and specially, more levels to explore. Good job!
