Could be more fun with a few quick usability and quality of life improvements. The enemy radar detecting you immediately on contact is a bit rough, I would give it a small time buffer so that the player has time to understand what happened. There was a point where I got a game over when visually the enemy was still turned around (while in code they likely turned around that frame and it wasn't around visually long enough for me to see it). This sort of leaves the impression of unfairness. Cool idea to potentially develop further.
