The first word that came to my mind after my first run was immersive. All the little details, like the date in the taskbar, the hilarious yet natural notes, a software named simply star_controller_exe to manage an intergalactic trade operation, and the WinXP-looking OS inside a spaceship, were amazing.
Gameplay is intuitive, and drawing paths that cannot cross each other was a clever way to create a challenge. My only suggestion is to make it a little more forgiving, perhaps allowing more than one ship to be lost before a game over. Excellent job!
