I like how there's different types of enemies that the player has to look out for. The projectile missiles are my favorite out of the three.
Though the friendly ships do help, I feel like they could do more rather than heal me. Something like Galaga where if I have another ship then I can use it to attack enemies.
I find the movement to be very slow, especially for a game like this.
Artwork for the enemies could use more work too. In other words, if the enemies are aliens then have two or three different assets of them in your game and make it look like you're fighting aliens. All due respect, but it looks like I'm fighting enemies that are either recycled content or old assets from a completely different game.
