I think there should be more science-y Alphys stuff. The determination experiments didn’t go well, obviously, but she is still a competent scientist otherwise, having created Mettaton’s body, a jetpack phone with interdimensional storage, the Undernet, and most likely a lot of the general technology in the underground besides the Core. I love cute stuff, otaku stuff, and Alphyne, but I also want more Alphys inventing things, Alphys experimenting with human technology, Alphys helping Frisk with science projects, etc.
