Very fun. The catching a fighting mini game was a little tricky to figure out at first, but a great use of genre fusion. I could see it being a good back and forth loop, with the catching and battle mechanics getting more complex in tandem with with the dungeon complexity.
As for the scavenger hunt, it was very satisfying to find the map and figure out where I'd missed. Making the ship symmetrical helped a lot too. And it was tense when I collected the last box, not expecting I still had to get back to the air lock.
