a skuy on a roomba on a rum

Changelog.

• Added the EXTRA mode. No reference card (Kosuzu’s still reading Nihon no Rekishi 14, “Sakoku”), and no Keine to tell you the dates if you lose. Try unlocking the 3 different (hard-coded) endings!
• A new theme unique to the EXTRA mode with a Hifuu cameo.
• Fixed an interface bug when the player hits Enter too fast.

Trivia

Keine’s surname in Ainu might be written as “kene”, meaning “alder” (the Japanese one). You might also transcribe her name as something along the lines of “kurka-retara-pet” but I don’t think this makes any sense.
