I liked this game! Some things to consider to improve are:
- The mouse sensitivity is very fast, I could lower it on my end but I wonder if a setting for it in game may help
- I thought shaking the trees and coconuts falling down felt like it wasn't too obvious, it only barely showed a coconut and could be a little confusing without checking it closer. I wonder if it could be made more obvious somehow just in case.
- Collecting an item while you already had one equipped also was confusing that you had to change the item slot to the empty one, this isn't mentioned anywhere on the itch.io page and there's no audio indicator or any other indicator to provide feedback that the action is not allowed or to change to the empty slot. Actually I think it should automatically collect it and not require to manually change the slot just to collect it, and it should just fail to collect it if your inventory is full.
Other than these above I think you did a great job on the game, it is visually very appealing and well done, graphically rich in quality and very immersive. I think it's a really cool game, nice job on it!
