Damnation Flame: Projectile that shrinks after hitting an enemy.

The ring's shader ensures thickness remains consistent when contracting and expanding. It's done by masking part of the mesh and offsetting vertices depending on the object's scale.

Ball N Chain: Especially challenging making the projectile look good on all angles, but still remaining a 2D look.

Sun Eater: Weak projectile
Exhume to Consume: Damaging AoE on health pickup
Wrecking Ball: Damaging dash
