Very cool. The only bug I found was that the slider resets back to 0 if you click and drag, but if you use the arrow keys, it stays where it needs to be.
Yes! I did find your game demo on YouTube/Murray's Discord. But I did send it to my friend to try, who doesn't have a programming background. I'm not really into resource sims like this, but it still hooked me in for like 20 minutes, so you've got some spark in it.
