This concept of linking things to build your ship is really clever, and fits the theme well! The art is fairly decent, and the gamplay is super simple, addicting and fun. Good use of sound effects and the physics movement felt fun to control.
Although feeling fun to control, the controls themselves were a little wonky and it took me a bit to get used to them. Acceleration is a bit slower than I'm used to so turning and getting to top speed was a tad difficult. Also, the game was very easy to get overpowered in early; you can balance this a bit more by having these joinable parts only be acquired by killing enemies (Like broken parts drifting in space).
Overall this is a really unique submission! Keep it up!
