Brilliant! Points are a completely made up and pointless metric that will nonetheless motivate players to take bad moves. They're the perfect metaphor for the motivations to not deal with climate change.
I understand, of course, that it's hard to put in everything you want to in a jam. I certainly didn't in mine, and the motivation to upgrade it dropped off exponentially afterwards, so you'll face no judgement from me on cutting content. That said, you've essentially identified the answer to your own question. "What would have made this game better than adequate for you?" -> "A meaningless score counter". It completes the metaphor.
Anyhow, good luck in your future endeavors. I'll certainly be interested in anything more you post to the site.
