So good! The clean presentation makes it easy to focus on what's important and the built-in tutorial was great and easy to follow. Like Benjiiiee below, I really liked how you have to be careful about how you attatch to other pieces - that it's not as simple as flying into upgrades to permanently add them. There could perhaps be a bit more "juice" but that's honestly a small complaint for how well crafted this is. Seriously nice work!
