A really good idea in premise, but the game had some pretty bad moments as well. Firstly, because your ship movement and enemy rotation is both controlled with the mouse it makes rotating enemies more of a risk than a benefit. This could've been resolved by ship movement being WASD or by time slowing during rotation. Furthermore, on one occasion the ship that I rotated was still shooting downwards, and therefore made rotating completely useless.
Despite the negatives, the idea and overall look of the game is really good! Well done!
