The game that is shown on the first panel is called "DoDonpachi". From what I understand, its a series, so I don't know which one this one is, my apologies.When I first looked at Undertale's combat system, the term 'bullet hell' immediately came to my head. I'm not really a player of this kind of game, but I heard a lot about this genre. From what I know, DoDonpachi is one of the most extreme example among all of them. So I figure that for Frisk who was able to dodge all near death moments, pretty sure he won't have any problems with this game lol.Frisk and Asriel are from "Undertale"
