Nice game, quite fun to play. I really like the 3D art and animations, music, and SFX. I agree with the comments of others, but there are a few things I have not seen being mentioned.
First, the game lacks some sort of progression. There are multiple ways to add this, for example, you could gradually increase the number of enemies, introduce tougher enemies, make the pilot travel towards some final goal, etc. Without it, the game felt like I could play indefinitely with not really that much of a challenge.
The other issue is related to the pilot themself. Do they have a purpose? Is there some way to control them or do they have some destination? To me, it felt the pilot just wanders randomly and also very slowly. In the first couple of minutes, I did not even notice there's a pilot because I just stayed at the beginning and did not need to move at all. I would either increase the pilot's speed or give them some actual path, so they can be more important for the game.
Overall, I had fun playing your game, good job on creating that in just 48 hours.
