XO-Planets is an engaging blend of rogue-lite, action platformer, tower defense, and RPG elements. As an action platformer, players can unlock abilities like double jumping, dashing, and wall climbing, all while wielding a one-handed weapon. The rogue-lite aspect ensures that each level is procedurally generated, offering a unique experience every time you play. However, be prepared for permadeath, which means losing all progress upon death, with some exceptions.
