Tsubame creates the red light green light mini game that Hajime thought up in PECO. However, Aoba sees the mini game and comments that something is lacking. However, Hajime sees the finished product and says something is lacking. Hajime isn’t able to figure out exactly what is lacking, and asks Aoba and Yun for help, but they still aren’t able to figure it out. Hajime asks Tsubame if she thought the mini game was fun when she was making it, and her answer makes Hajime realize what’s missing, but Tsubame then worries about how the extra work is going to reflect on her...
So this is what it's like 
to create something from scratch.
هذا هو الإحساس بصنعِ لعبة من الصّفر إذاً
So fühlt es sich also an,
ein Game von Grund auf zu erschaffen.
¿Así se siente hacer
un videojuego desde cero?
¿Esta es la sensación de hacer
un videojuego desde cero?
C’est donc ça, la sensation de créer
quelque chose à partir de rien.
Allora è così che ci si sente
a creare un gioco dal nulla!
Então é assim que se faz um jogo do zero...
Вот что значит делать игру с нуля?
