Mock-up screen for my Shoot 'Em Up

The theme for my Shoot 'Em Up was in the space.

So there are many kind of spaceship shooting each other.

The player has to defeat all the enemies and the boss to complete the game.

There are some chances to drop power-ups and med-kit from the enemy when it was destroyed.

The player can see how much hp left and how much score they have on the upper-left of the screen.
