Interesting concept at first glance. Never thought about a spaceship shooting game with gravitational field force pulling the player that poses an extra threat.
The art of the player and the enemies' spaceship doesn't look awkward and are actually surprisingly detailed.
The music and sound effects fit this game a lot and I enjoyed it.
But it is extremely hard to control the player. Drifting + only attacking front makes this almost impossible to play. 
Especially when I'm stuck between 2 enemies spaceship like this
Also said in previous comments on this page, the enemies' hitbox is too small. Only the center part is the collider. The wings aren't. Along with all other factors, escaping instead of fighting is encouraged, thus leading to a relatively boring gameplay.
Would be better if
- Can attack to all direction where the mouse cursor is
- I seriously doubt using acceleration to move the player is good in this case. Gravitational field force is cool using acceleration, but not the movement.
- Enlarge the hitbox of enemies.
- Would be better if there are more stars that pull the player considering the size of the map.
Anyway keep up the effort :D
