A graphical game using excel spreadsheets as pixels is very cool and fun. But given how easily turn-based strategy/resource management tasks are actually legitimately suited to tracking in a spreadhseet, I would have been intrigued if it had used the native excel visuals more, with formulas in cells, and numbers all plainly present, with perhaps a rudimentary graphical map where a square sheet cell was a movement square.
Also, just a future-history predication: once someone makes minecraft in excel, the singularity will have arrived.
