I'm blown away. I totally was not expecting something this polished from the cover image.
Gameplay: Suprisngly really addictive. Although I didn't feel the goal of winning a shipping was a big enough of a reward as nothing changed. Maybe if you got a upgrade or something it would be better, but I seriously loved playing this game.
Art: The menu and tutorial art was amazing. The UI you chose fit perfectly together. None of colors was offsetting or anything. It felt extremely polished. On the other hand the game itself could use some touching up. It would be cool if there was one color palette and style for everything and if it fit into the space art style like your menu.
Audio: The sound effects and music was perfect for the game!
Theme: The idea of infinite but, still limited space was great, although the space ships doesn't really fit.
Devlog: Very pollished, informative, and entertaining!
