Ball X Pit
It was the 12th most-played game in the June Steam Next Fest: Ball X Pit by Kenny Sun and Devolver Digital. This combination of Arkanoid, Pong and bullet-hell roguelite really makes it all about balls.
Ball X Pit is a 'brick-breaking, ball-fusing, base-building survival roguelite' set in a world where Ballbylon has fallen. Following the destruction of the city in an unexpected event, only an ominous pit remains. Treasure hunters seek their fortune in the city's tombs, diving deep in search of its scattered riches. However, the pit is also home to hordes of savage creatures. Armed with an ever-growing arsenal of magic-infused projectiles, players must battle their way through multiple levels of increasingly challenging obstacles in order to rebuild New Ballbylon.
