Neon White is a first-person shooter and puzzle-platforming game developed by Angel Matrix and published by Annapurna Interactive.

The game uses playing cards to represent weapons, which can be discarded to perform special moves like double-jumping and dashing.

[10] White receives daily missions from the angel Mikey, and meets up with old crewmates of his, all while dealing with amnesia that prevents him from recalling his past life.

The player traverses the level by running and jumping, collecting Soul Cards lying about in the open or obtained from defeating demons.

Following the confrontation, White learns of the counterpart Book of Life, and decides to seek it out as his suspicions about the competition and the Believers mount.

Green returns to Outer Heaven and steals the Book of Death from the Believers, preventing them from detonating the Neons' masks.

Lead designer Ben Esposito created an initial prototype of Neon White as a first-person shooter in 2017 while he was finishing development of Donut County as a distraction from that work.

[9] The card idea concept led to the game being what Esposito called a "card-based arena shooter with a lot of randomness built in".

[12] Additionally, they set themselves a design goal that each level had at least one major shortcut that would be necessary to achieve the Ace medal rank in the absence of any other mistakes.

[14] He brought on team members to help on the game's visual and character design, including Aevee Bee, Ryann Shannon, and his wife Geneva Hodgson.

[14] In May 2022, Steve Blum, Alicyn Packard, Courtney Lin, Ian Jones-Quartey, SungWon Cho, Zeno Robinson, Salli Saffioti, Ben Lepley and Bruce Barker were announced to have voice-acting roles in the game.

[19][20][21] Eric Van Allen of Destructoid praised the game's angular aesthetics, philosophical story, speedrun-incentivizing level design, and endearing characters and voicework, writing, "[Neon White]'s a blood-pumping, speed-infused anime shooter with style and a decent bit of heart.

"[22] Eurogamer's Oisin Kuhnke recommended the game, lauding its story, themes, and anime influences while primarily praising its speedrunning-centric core gameplay loop, stating, "Neon White has some of the best level design I've ever played in an arcade-style game...the adrenaline I felt when I squeezed in that first place time within less than a millisecond wasn't like any I'd felt before.

[25] GameSpot's Richard Wakeling appreciated the title's replay value and inspired card-based mechanics while calling it "a flawless marriage between level design and player improvement", but noted the slow-paced story and weak writing.

"[27] Scott McCrae of Nintendo Life gave heavy praise to the intense and satisfying gunplay, great writing and performances, high replay value, fantastic visuals, and energetic soundtrack.

"[30] Shacknews' Morgan Shaver praised the agency the game gave to the player and the experimentation it encouraged, writing, "You really get a nice, exhilarating speedrunning feeling in Neon White with the multiple ways in which you can clear a level, both conventional and unconventional.

[34] Neon White's soundtrack was created by Machine Girl, who was specifically sought after by lead designer Ben Esposito after hearing their 2020 EP RePorpoised Phantasies.

[42] Lead artist Matt Stephenson accepted after determining that Esposito wasn't "just some kid in his bedroom making a video game", and began sharing a large quantity of unfinished demos to work through and use in the game after Esposito stated that he wanted the soundtrack to continue in the direction of the sound of RePorpoised Phantasies.

[44] During the later stages of development, Machine Girl began live touring while still working on music for the game, and Stephenson would create chiller compositions in order to de-stress.

"Peace of Mind", the main theme for the game's hub world, was created during a particularly stressful day for them as they were running "super late" for a show and one of the van passengers had become car sick.
