Very cool game, polished both mechanically and visually, at least for the world elements like trees, rocks, water, ecc...

I found some problems and have some suggestions if you plan on expanding the game more:

1. If you start hitting something then stop and walk away, the popup window with the remaining "HP" of whatever you were hitting stays on the screen forever, without even pointing to the direction of the object you were hitting, like this:

1. Try to make the assets you used more cohesive in their style: the icons for the resources are very realistic, the UI is very minimalist, and the game is in a middle-detail low-poly style, maybe try to make the UI and the icons stay consistent with the simplistic and colorful style of the game environment.
2. You can walk on water, then gradually go underneath water by just a little bit, and then ending up out of bounds and falling down infinitely if you go too far away from the island: either add some invisible barriers or make the player drown and thus respawn if he gets too far away from the island.

The game felt very polished and nice to play, though I can't tell whether you made everything yourself or used some assets both for the visuals and for the gameplay and game feel, since no credits were given, but in both cases, good job on the game!

Interesting game! Very polished in some aspects
