I enjoyed the core gameplay a lot! I like these kinds of resource management/trading games and I definitely think it's a solid base to build on. A nice simple visual style, nice sound design and music too.
Main critiques I have is that the volume was pretty loud and there were no audio settings, and that there could be some quality of life improvements with turning in/collecting resources, though I understand with the time constraints.
Overall, it was enjoyable! Great work!
