Solstice is an isometric-perspective puzzle game in which the player controls the wizard Shadax, who must navigate 250 rooms within the fortress Kâstleröck and assemble the six pieces of the Staff of Demnos to defeat the baron Morbius and rescue the princess Eleanor.[1][2] Shadax's basic abilities consist of jumping, and picking up and dropping objects.[3] Early in the game, Shadax can obtain a pair of magic elfin boots that augment his jumping height. He is additionally equipped with a few beakers that can be used to store four different varieties of potions; these potions can either grant temporary invincibility, destroy all moving objects in a room, freeze time, or make invisible objects visible. At the beginning of the game, the beakers can only hold up to two doses of a potion each, though upgrades can be obtained later on. Any number of potions can be cast simultaneously within a given room, but the spell(s) will only last as long as Shadax remains within that room; any effects from the potion(s) will disappear when the room is vacated.[1]
