Crystalysis

Arena defense

Crystalysis is a fast-paced slingshot game with survivors-like builds and roguelite elements. You defend a crystal in the middle of an arena by charging a ball and ricocheting it through waves of enemies. It plays entirely offline, with online leaderboards available; its modes include endless runs, timed runs that end with a boss battle, and a daily run on a seed shared by everyone.

Builds and weapons

You pick up upgrades each level and combine weapons, passives, and Aspects into a build. Matching passive tags can feed into weapons and other upgrades: fire, ice, kinetic, orbitals, summons, and salvo are among the tags. The game has six artifacts that change how you control the ball, including the Ball, Cannonball, Katana, Saw, and two Tether options. Upgrades and weapons can be unlocked and leveled past their limit.
