Cool implementation of the flatland idea. I saw a couple of other entries were also inspired by it, but I think this one did it the best - the thin line (rather than the colours taking up the whole screen) and the patterned walls made it easier to navigate and perceive as space.
Definitely interesting to wander around and talk to people and I enjoyed how you worked in aspects of the book like how the shapes have to be careful around sharp angles hehe. A cool atmosphere overall.
