Steps to reproduce:
1. Open attached project in the comments
2. Open 04_Gameplay.unity scene
3. Enter Play mode
4. Observe as the spaceship movement is very flickery, especially if going to the edge of the screen
5. Disable Assets > Prefabs > Spaceship Polygon Collider 2D or Simulated setting in the Rigidbody 2D component
6. Enter Play mode
7. Observe as the spaceship movement is now correct
Actual results: 2d physics causes object movement to flicker
Expected results: getting smooth movement using 2d physics
