Wow, that's some wild lore, and it's impressive you managed to make a full opening cut-scene! I like the art style and that rotating planet is quite iconic. Obviously it would've been a lot to get all those RPG mechanics in there for a game jam, but you've set up the structure for a lot of interesting systems, so this could be the beginning of something great!
Also, just for future reference, there's a weird bug where if you come out of full screen and then open it in full screen again, the game gets rendered in a tiny square. It confused me for a bit before I refreshed and reloaded, which fixed it.
