This is so good! You are definitely going to be one of the winners. Some recommendations:
Improve the enemies. Instead of them not colliding with any obstacle think of implementing a way for avoiding them. Also I think the fighting system needs an improvement. And reduce the spawn rate unless you are going for a hard game on purpose.
The two shops in the middle of the island don't convince me. Maybe you could change it to a boat that appears periodically?
Also I think the recollection system can improve.
I'm pretty new in this so don't take this recommendations seriously but overall great game
