Nice theme and well executed, as always you tie a lovely final product together. I like the concept a lot, and see a lot of potential in it feeling really fun to play. The choice between plundering and upgrading already feels very good, the docking especially has a really comforting, nice effect. Overall the gamefeel is great.
The exploration aspect also works really well once you get a bit deeper into the game, and it's really cool to start to realize that there is so much more off to either side.
I have a hard time getting into it everytime I try it, largely because I think the controls feel just a bit too heavy to me, and I feel a little too slow at the start. This is, I think, largely exacerbated though by feeling frustrated at loot. When I shoot something from any distance, the loot can fly off in two separate directions and I'm too slow to catch any of it. Even if it conveniently jumps up and comes back down again this takes seconds, and makes looting more of a chore than a joy to me. I'd love to see a much more generous auto-collect feature maybe that makes loot fly towards the ship, and generally I wish the game would make me feel a little more epic for being a sky pirate, especially against small fry enemies, so that I want to engage in looting and combat and plundering all the more :D
Generally I think the 'starting area' could be a bit easier, either by virtue of fewer enemies or a bit less restrictive control on the ship.
But of course all of this is feedback based on the fact that it's a solid entry as always, and feels very complete!
