Unique and pretty fun idea and the fact that you made absolutely everything by yourself is extremely impressive.
However there's a couple issues I encountered:
-ships can (seemingly very rarely) spawn on top of an obstacle, crashing instantly
-the ship controls feel a little inconsistent but that could just be me
-it is unclear at what point a ship will lock on to the beacon, sometimes they just ram into obstacles while in this state since you can't really control them
-the crash sound makes every bone in my body snap, take that as you will
Good job overall though, most of these are nitpicks
