There are a lot of features in this game, but I feel like more focus should have been placed on the main gameplay! I like the different worlds, the ship travelling, all the different enemy types, but the main parts of the game are a little boring. Right now, combat is just occasionally pressing a button, and resource gathering is just walking around. There needs to be a bit of extra complexity! Some simple things you could add are making it so that you can defend enemy attacks by timing a button, or maybe some special movements techniques like dashing or rolling.
