@Mickey,
First off thanks for the top notch feedback, man!
Most everything you listed are things I've considered or already have planned and am working on for the full release. A world map of some sort and a minimap is definitely on the radar. I've nearly tripled the jump height and even added a second, double jump feature which really makes getting around feel more convenient and allows me to hide the telepod behind a crafting menu or something later on since it's not a necessity anymore.
While I'd love to add the ship turn animation, I'm just not seeing it in the cards. I've already started work on creating modular ship parts that can be randomized and spawned in so players can discover new ship types at all times and run into hostile pirates aboard them as well. Because of this, adding a big fancy, complex turn animation probably just isn't going to happen. Instead, I plan on building more clever sails that rotate and tilt based on the direction you're flying to give the ships a unique bidirectional function to them that just makes sense in the world.
I think the file size is so large due to how Gamejolt wants me to pack both Mac and Windows builds together and of course all the art (png's) and the audio. I have two nearly full length tracks in the game already and plan on doing a lot more for the full release. I was a little worried about the file size, and maybe I'm alone in this, but I never look at the file sizes when downloading at least LD games because I just know that they're going to be tiny. And I think once someone's already clicked download, they're probably not going to cancel it after that. Though they might leave it to download and forget while they play another game or two.
But thanks again for the great review. I'm hoping you follow the game on Game Jolt and get to play the full thing in a few months when it's ready.
