Hello!
My idea is change the game style: The raft now seems stay in one place and the waves coming toward the raft.
What is my idea the raft moveing in a linear way and sometime reach an islan where the player can hook the land to anchor the raft and gether what he can from the island.
Maybe lower the loot what now the players can get and this way the island"raid" is could more important.
Secound idea finding other floating rafts and "raid tham"
I know its not easy to code maybe in time.
Kep up the good work for this awesome game. :)
