This is a brief lil arcade shmup, where you fight bosses while riding fixed tracks that orbit around them. True to the name, there’s only one button for player input, which has different effects upon your movement and shooting depending on your equipment loadout.

The main campaign is pretty brief at like 3 hours, but I really had fun with it. There’s great variety in both enemy attacks and selectable playstyles for your ship, the challenge is tough without ever feeling punishing, and you can unlock alternate color schemes for all the different pride flags. There’s even a whole extra roguelike mode that you can dip into whenever! Definitely recommended.
