Blockperson in HyperCubeWorld is a sequel to Blockperson in Cubeworld
I am currently working on a much larger sequel, which is currently on hiatus due to depression about a significant bug that I need to fix and then reimplement every single environmental puzzle in the whole world.
That last bit is quite daunting given my general lack of energy after getting home from work.
In the meantime, please enjoy this one :)
