Hello, thank you for playing! Yes, the "Skip" button is always great for VNs, be it long or short. Looking back I do think maybe a few more menu options would have been nice, even if they were simply the illusion of choice, but having lost about 3 days at the start of the jam made me a bit pressed for time, so duly noting that for next time if I submit a VN! I'm also really pleased you enjoyed the voice acting. Post-jam update, I do intend to add a few unlockable bonus features (it will correspond to the same persistent.data as Epilogue, and if you already got it, updating the game the persistent.data will remain since it is not stored in the game itself but somewhere else on your computer--so if you delete and put the new version, it will correspond with the new version and already be unlocked). I'll probably add the translations for all of the twins' Japanese dialogue as well as the language barrier bits. But yes, the joke was that you couldn't understand the twins, hence also why I used actual kanji and hiragana instead of romaji.
I'm glad you seemed to enjoy this game overall. I feel like the game is sort of a hit or miss for some. You'll either love it or hate it, but I am glad despite its flaws that many have mostly had a positive experience with it. The frustration of the RNG and need to skip was kind of part of the bad aspect of the game by design, but whether this works for or against the game is very subjective haha.
