Solid in concept, but the execution felt underwhelming.
I initially though enemies would come from below so I was looking down and lost a couple of times not knowing what hit me. But then the gameplay turned out to be "hold D + hold Left-click + drag mouse". Like a regular shooter on ground, but with no thinking. And very, very tanky enemies.
Would be fun if it was more focused on falling and shooting down. When I saw the two guns on the cover and read the description it made me think of Beat Saber, but with moving down and with guns instead of sabers! I'd love to play a shooter like that.
