10450 high score, Feels quite polished for your first game in a new engine, good job!
I have some feedback
- It would be nice if the ship moved continiousely and not in steps, because then it feels weird considering that some of the bullets have a diagonal trajectory.
- (This is a minor one) The stars moving when you have to choose a powerup makes me think for a second that the game isn't actually paused.
Anyway, GG and good luck :)
