Non-spammable achievements

[jeremyckahn]

M8theone on Discord raised the good point that many of the achievements in the game can be reached by simply spamming through days. The achievement "A Big Average Rainbow" is different, as the player needs to actively think through how to complete and work through it:

farmhand/src/data/achievements.js

Lines 221 to 233 in 8269294

	((
	goal = 1000,
	goalItem = itemsMap['rainbow-milk-2'],
	reward = 500,
	rewardItem = itemsMap['scarecrow']
	) => ({
	id: 'sale-goal-2',
	name: `A Big Average Rainbow`,
	description: `Sell ${integerString(goal)} units of ${goalItem.name}.`,
	rewardDescription: `${integerString(reward)} ${rewardItem.name} units`,
	condition: state => state.itemsSold[goalItem.id] >= goal,
	reward: state => addItemToInventory(state, rewardItem, reward, true),
	}))(),

(Though perhaps that's a rather extreme counterexample.)

The game should have more achievements that require thought and strategy. What are some achievement ideas that might provide players with more interesting challenges like this?
