I really enjoyed this prototype. The whimsical fun fact dialogue was fun and kept me wanting gain knowledge. I like the idea you implemented of the different milestones formed from different button combinations, and overall having different effects on the stats of the emissions and the character and I would lean into that more. Consider adding dialogue for each button, they don't have to be as in depth as the fun facts, but something to keep the player clicking each button multiple times to have a more immediate payoff. Also consider having more buttons that have a more drastic upside and downside to add more difficulty for the player to balance out the various stats, like take the vegetarian meal for example, it has no real downside, so there's no reason for the player not to click it, perhaps those meals cost more money than regular meals. Make the player think of ways to balance those stats. This has great potential so far, keep it up!
