The "Nullscape" is a realm where people, known as Players, must collect "Gifts", before escaping to the "Beacon". In the Nullscape, there are platforms holding Gifts, which Players must reach to acquire them, while still avoiding the Enemies. Once all gifts have been collected, a Beacon opens, allowing the Players to escape back to the Temple.

The Nullscape is divided into "levels", and as Players go deeper and deeper into the Nullscape's levels, more Enemies, Curses, and Upgrades become available to them, presenting dangerous threats, but beneficial rewards.

However, below the platforms lie the Void, and much like Enemies, when Players enter the Void, they die. There are also Tripmines, fake Gifts that explode upon impact, killing Players unaware of their surroundings, Seamines that are larger Tripmines which can also be used as platforms, and Void Implosions, a result of the Nullscape growing more and more fragile.

Even despite the Beacon being an escape from the Nullscape, the Beacon's light is entirely up to the players to go to. There's also another effect that spawns from the appearance of the Beacon, Golden Gifts. Golden Gifts spawn exactly where Gifts were, and Players can collect them. However, due to the instability of the Nullscape, once the Beacon and Golden Gifts spawn, platforms begin to break.

Aside from the Nullscape itself, there is also a Temple which acts as a resting place and intermission area for Players to recuperate, pick new Enemies and Curses and purchase upgrades. The Temple, however, is also a place for Enemies to reside in, but instead of killing Players, they remain docile enough to be interacted with, and any mechanics tied to them are disabled, rendering them effectively equal to Players.

The Temple contains three pedestals, allowing people to pick between three Enemies or Curses. Once a selection has been made, The Orb appears. The Orb is a sphere that when touched, automatically sends all Players directly to the Nullscape, including new enemies the players have picked. However, the sphere only appears once Players have decided on an Enemy, or a Curse.

The Temple also expands, the deeper Players go. At first, it's just a ruined temple with small tables and bookshelves tipped over, but as Players grow stronger, the Temple expands into a "home" for the Players, having personalized rooms for both themselves and the Enemies.

Enemies are adversaries that actively try to kill the Players, sending them back to the Temple, where they can watch as the remaining Players collect Gifts. However, during Intermission phases, before Players pick their Enemies, Curses, and Upgrades, they are calm, and Players can interact with them.

Aside from Enemies, there are also Curses, and Upgrades. Curses increase the strength of the enemies, while Upgrades increase the strength of the Players. However, to acquire Upgrades, Players must have enough Golden Gifts. Upgrades can also fully change how a Class plays, such as Ninja Belt, which grants an alternative ability that 'evolves' the Class, Shark Tail, which 'evolves' the Class even further by giving them a way to gain high vertical mobility, and Miniature Hourglass, the final upgrade to a Class's skillset, giving them a unique passive.

Players have one more method of variety, those being the Classes they adopt. Players can pick Classes before they enter the Nullscape, changing their skillset accordingly. Divers can dive, and they are the default. Chargers can charge forward with rapid velocity, Spirits can temporarily escape their physical body to avoid threats, Grapplers can utilize a grappling hook to either reel themselves in or swing under platforms, Gliders have hang gliders they can use to glide, Bruisers can repel Enemies by striking a pose, Wanted's have increased double jumps, and Prisoners are for the people crazy enough to not want an ability tied to them.
