Pseudoregalia

Pseudoregalia is a 3D platform game/Metroidvania hybrid, where the player character, Sybil, is tasked with making her way through the Castle Sansa. The game's environment is structured in an open-ended manner, with many alternate movement paths that can be made available to the player by upgrading certain abilities. The character movement emphasizes fluidity and responsiveness, with a focus on running and jumping.

Sybil begins with a sword called the Dream Breaker, a jump, a ledge grab and a slide; abilities found in the castle add a slide jump, a wall kick, a somersault, wall riding and a ground pound. The moves can be chained: a ground pound leads into a higher jump, while a slide jump increases the height of a somersault and pushes a wall kick further from the wall. Certain obstacles require specific upgrades: weak floors are broken with the ground pound and some walls only with a charged sword attack, and these barriers block the paths to the five major keys, the game's only mandatory collectibles. Combat is built around movement, with a basic attack and a healing ability, a charge attack and a magic projectile obtained later, and two boss fights.

Sybil, upon arriving in a mysterious castle's dungeon through the use of a golden mirror, expresses vague concern about her punctuality and an unknown goal. As she travels through the labyrinthine structure, various NPCs and signposts point to a far off tower with a princess in need of saving.

After obtaining all 5 Major Keys, and the upgrades required to reach them, Sybil is able to open the door at the top of said tower where the princess awaits. However, upon reaching her chamber, the Princess attacks Sybil and is soon after defeated. Afterwards, the castle collapses and it is revealed that the events previous were only a dream being had by someone who seems to know the Princess, who thanks Sybil for waking him up and wishes her luck on her next adventure.

The initial version of Pseudoregalia was developed in around three weeks as a submission for the Metroidvania Month 19 Game Jam, which took place between February and March 2023. io. An extended, "full" version of the game was made available to purchase via Steam on 28 July 2023. Compared with the jam build, it added the Twilight Theatre and Listless Library areas, reworked the layout of the Underbelly, and introduced further movement techniques such as the somersault and the wall kick reversal.

According to the developer, the production of the extended version took four months, and since then, there has been an update adding an in-game map. That update, released in March 2024, added the Memento item, which provides a top-down map of each area, enlarged the entrance to the room holding the Underbelly major key, and introduced time trials that unlock an additional outfit for Sybil.

Following its release, the game sold 28,000 copies by September 2023, a result the developer found unexpected. By August 2024, it sold 200,000 copies and had 10,000 reviews on Steam.

Pseudoregalia received acclaim from various professional outlets ahead of and following its release on Steam. Rock Paper Shotgun praised the flexibility of motion it offered, describing it as "super-slick" and "[looking] absolutely fantastic in motion". William Hughes described it for The A.V. Club as "an indie gaming winner" and as a reminder that "having satisfying gameplay can overcome almost any other issues". Dustin Bailey of GamesRadar+ stated that it looked like "an incredibly well-crafted game laser-targeted at my gaming wheelhouse".
