I've already finished the game, and I think it's absolutely fantastic, especially for an early release. So these are just ideas of things I'd like to see in the future.
- More actions on ships (maybe decorating the interior, a useful bed, accessing the inventory from a chest, being able to talk to people, climbing to the eagle's nest... just more interaction)
- Increase the weapon movesets. (Right now they're a bit basic, more combos with heavy attacks, specific moves after dodging, you know, more Soulslike)
- Terraforming (improving the use of the shovel to modify the environment)
- Mannequins for armor and weapon racks for weapons (let me show off everything I have, don't leave them gathering dust in a chest)
- More exploration puzzles (I really liked one of the temples, moving jars to buttons and braziers, with a floor that broke; I'd like more of that style)
- Targets and practice dummies to test weapons and builds.
- More NPCs and base management; force us to provide them with beds and food. Also, NPCs for the ship's crew, with different skill levels that modify gameplay (faster cannon reload, improved aim, increased search radar, better fighters for boarding actions).
- More bosses (the three boss fights are excellent, especially the second. I'd like more bosses, and for them not to be so far apart. Many hours pass between them; perhaps mini-bosses in specific biomes for points of interest).
- Harvesting (let me replant whenever I have seeds; it's a pain to have to replant every time).
