Hi! That’s great, thank you! I’ve added "ei" to the credits.
About the swipe feature: when you open an ending, click on the art to make it full screen. Then you'll see an arrow on the right — just click it to swipe through the gallery.
You can see how it works in the current version (0.0.9) with endings like:
"16 and pregnant", "STFU Tactical Nuke Incoming", "The Doctor's Toy" (Wanderer)
"Cheater" (Kazuha)
"Frozen Fool" (Venti)
Hope this helps! Thanks again for your contribution!
