Hey, pretty nice start to a game here! I liked that you could traverse via a submersible but also get out to extract resources and attack enemies. It took me a little bit to get used to all of the controls because there's a lot going on but I'm glad that you had the controls available in-game to reference, it was a big help! Some of the building aspects I struggled with, I'm not sure if it's just not all implemented yet or if I ran into bugs, but the idea is really cool either way. I love the underwater bazooka and definitely blew myself up with it more than once... 😅
