Several of ENA's animations throughout the game mimic shots from the music video for the 1981 song "Taiso" by Japanese synth-pop group Yellow Magic Orchestra. This appears to recall a prior trend from the original web series where ENA would repeatedly mimic scenes from the music video for American new wave band Talking Heads' 1980 song "Once in a Lifetime".

In a livestreamed playthrough of Chapter 1, Dratula's voice actor, Twitch streamer and YouTuber Vinny Vinesauce, indicated that his dialogue was recorded with little context regarding when and where his lines would be spoken. Consequently, despite the volume of material provided, he did not realize that Dratula would be the first character that ENA encounters until he played the game for the first time on-stream.
