You might as well look at HyperRogue, where the whole game happens to be on the same model.
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.
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.
Nice concept. really unique experience. so smooth.
