Hi. I don't like this genre, but I'll tell you what I've noticed in other popular games of this genre.
-Weapons have colorful and different efects. And there are a lot of different ones
-Your ship can pick up different boosters that vleyayut on gameplay, such as shields or invulnerability, all this is also brightly glowing.
-Enemies have different shapes and attack options and very arko explode.
-In recent games you can improve or change the ship.
The common feature that I noticed is that there are a lot of very bright moments, probably this uaditoroya likes it.
