Like everyone I also agree with upgrades and an upgrade tree. I also think there should be a targeting arrow above the water, because it is very hard to keep track of where the boats are located above your head, also a larger map for a larger whale would be suffice
very inspiring, imaginary and almost resembles the art of dad and me which made it so interesting to play all in all good work I sure it took awhile to write and code and I appreciate the hard work 5 out of 5
