Cute game! It reminds me of a prototype city builder/gardening game I was playing around with.
Some notes on your current stuff:
- It's difficult to get a ground panel going the correct way I want. I'll be trying to close in a shape but it'll keep wanting to go the other direction of what I need
- Having to close in shapes is boring. You should let players build whatever they want, might work well with village behavior once it gets more complex
- I noticed almost all my villagers were pathing to the same two trees, even ones spawned from far away villages
- Auto-collection of materials would be nice. That and you should enable 'Run in Background' under 'Edit->Project Settings->Player' so I can alt tab and still get materials.
