I've spent quite some time playing, and I really liked what I saw. What stands out the most to me is the algorithm you've created to generate spaceships. It looks very organic and real, generating spaces similar to rooms and compartments. The graphical aspect is the second thing I liked the most. This tileset fits perfectly, and if you've made it yourself over these 7 days, it adds even more value to your work and dedication.
Regarding the style of play, I think it fits perfectly, and you've managed to apply the space theme within the traditional roguelike category. I congratulate you on your work; it's evident that you've spent hours on it and have achieved a complete and fun product.
