I like the interpretation of the theme, it's a very fun game with a cool and hype BGM.
The only 2 things I hope:
1.) Harpoon should be on top of the list since it's the cheapest and the only way to let the player do anything meaningful progress, I was stuck for a while thinking that the scrap will gain over time when I realized that I can't build the first(top) things come to the list.
2.) It will be best if the ship has some way to destroy the obstacle on the road, I found some time it's impossible to steer and avoiding from the obstacle.
