I really like the approach but it'd certainly be nice to be able to use alternate topologies.

Also it'd be nice if there was an underlying grid plotting the metric/distance function to help conceptualize distance/relationships better when you get to the edges.

You might as well look at HyperRogue, where the whole game happens to be on the same model.

Loving the smoothness of this. One concerning thing is overlapping notes – I don't want to be fucking around with trying to move the canvas just right to read a note under another note and there doesn't seem to be any other simple mechanism to resolve this (especially for larger blocks/images). The 'untangle' feature doesn't really solve this.

It's Greg Egan's notebook!

Nice concept. really unique experience. so smooth.
