Very interesting! Abbot's Flatland was my first thought for the jam theme too though I ended up with something more conventional.

Cool implementation of the Flatland concept - I have also thought about making a simulation of Flatland before - turns out it is pretty difficult to comprehend haha. I had an issue where since the mouse isn't fixed to the centre of the screen I couldn't turn a very wide radius. But you don't really need to move a lot so it wasn't much of an issue.

I thought maybe the dialogue should start automatically as I found myself wandering around for a while before remembering I was supposed to press space!

Wow very intresting game. Nice explanation of geometry, space. I had a feeling like i was back in elementary school :) . Thank you :)

Interesting dialogue, but I'm not sure what happens. XD 

The idea of implementing the theme in this way I find quite successful.

Really immersive experience. The dialogue was great and the minimalistic line view worked well. I had to switch to top view several times though as it was hard to move around in that perspective.

I'm not entirely sure whats going on, but that is to be expected. It's defiantly a good take on the concept.

Also, I'm slightly biased in your favor.
