Game idea 5: Galaga rhythm game

• A Galaga-inspired mobile rhythm game where you need to destroy rockets that are flying towards your space ship by tapping them on the beat. Then at specific parts would be the actual Galaga part where you need to remove as many enemies you can/damage the main enemy (likely a boss) by either shooting it like Galaga or tapping the missiles to redirect them. 

(This one kinda feels like what Geometry Dash is to The Impossible Game, except it's completely transforming Galaga.)
