Cool game! The style was simple and clean, the movement feels really responsive. I like the concept of buying a discounted spaceship and taking it to battle, it's a fun idea!
This is just my opinion but for a shooting game like this, I think the enemy's bullets should be larger? A lot of times I can't see the bullets, so I don't know where to move. Doesn't need to be too big, just maybe a bit wider and not just a thin line. Also, the screen shaking became too intense at a certain point, it made me dizzy.
