For anyone who finished this game and got to the gallery mode, make a back-up save before attempting to use the two Krozel post-defeat events in them. The game does not teleport you to a compatible map for the events, and will get stuck when it tries to move two miss-targeted NPCs in the gallery into spots that it can't do so, forcing you to restart (either by closing the game or pressing F12).
Unless there's a fix in a different version or someone patches that error out by scripting in a teleport to a proper map for the event, losing to the character's the only way to actually see the two events fully.
That aside, there's quite a bit of untranslated content in this partial translation, at least from scouring the project in RPG Maker. There's a few missing things I noticed during normal gameplay, mostly Junk Part chests and a few stray lines from some unimportant NPCs and some of them post-event. That aside, quite a bit of the content I'm uncertain of how to access: most of it relates to characters known as Karen and Nicole, and what looks like a more medievil-ish fantasy RPG town. I'm assuming most of it is leftover content from a previous title or some such and that's why the translator looked the other way.
Also, no one should really worry about the time limit: The earliest day you can start getting endings on is the 16th, and the earliest day you can legitimately "win" is the 19th, where the ending will be extended (and apparently considered Good) if the game considers your character to have lost their virginity (there's a couple of events that increase your vanilla sex counter but don't actually update the string the ending checks: the last ones in the unpopular beach boys and the train molesters series).
If you manage to get all the way to the 30th day, you can access a new area where you can fight a final boss that is otherwise unavailable earlier if two or more of the four main antagonists still live... that is part of the partially untranslated content. Oops. If you fight the earlier available final bosses here, their dialogue is also untranslated- everything about the 30th day is untranslated, save for your visit to your helper's hideout, actually. I guess the translator didn't think anyone would bother letting time run out.
Edit: Oh, if you chose to play again via the New Game+ feature that keeps your stats and the like, examining your bed at night reveals a menu that lets you skip to the 16th or 26th days. It's untranslated, but: the first option sleeps until the next day as normal, the second is still the cancel option to leave the menu, the third skips you ahead to the 16th day and the fourth to the 26th. You'll get asked to confirm the date change if you choose either of these (first option confirms, second cancels), since it's one way only. You'll miss out on the yen and items you would've gotten on the days you skipped, also.
