I like the game so far! :) It's like a much more accessible Dwarf Fortress. 58 days is my best so far.
Though I'm not sure if I'm doing farms right. (You just build them and they make food? Do they have to be near lakes and pools?) Also, is there a way to toggle off your building tool besides hitting escape twice? Switching back to harvesting with one button would be nice. It would also be nice to be able to click and drag to apply one command to multiple tiles (to chop down a bunch of trees, for instance). Or un-fix/harvest a misplaced wall or door? (Your description says 'take down what you don’t need' but I can't find that tool)
But it's amazing that the engine is ~9,999 bytes as is. Impressive feat!
