This has a great little resource exchange system! It took me about 45 mins to get to the end though. If I could swim about 10x faster I wouldn't have minded as much. It's satisfying to get to a point where you've automated generator production, but I found I was just waiting for it to sort of happen. I would have loved to explore the world a bit more (the minimap was a lifesaver btw - almost forgot where I left my mill), but the slowness was a bit of a disincentive to do so. The cutscene at the end was nice! It was cool to see all the things I had placed in the environment, though some of my drills were offsceen unfortunately.
