Gradius was one of my favorite games as a kid, and this side-scrolling style of shooter is something I play a lot of. But I've actually never seen a reflection mechanic that rewards you for staying still until now. It's intuitive, feels good, and is kind of obvious despite being so unique.
I'm really fond of the player sprite too, the whimsical spooky nature of the enemies, and the cute music. Looking forward to beating this one.
Thank you for making it!
