Tulip just denies me, can't go with them because "hurr durr you are too big to come with us" max affection and everything.
Meaby the steam version what i am using is just bugged or something, didn't even get the achievement for helping galan.
don't know about the dungeon can't remember if i have ever done that.
harmony was you do the normal route (fix the ship, get the sail). Meet the vampire, lie about the relationship with the vampire when the elf ask of it, max affection with both/do their quest's if possible (some are repeats), (don't be a dick to them in dialogue), vampire loves booze (limited) as a gift, when they want to speak to you go there just to be sure. wait until the last day and that should be it. Did the endings like a year ago so everything isn't in good memory. It's just 1 ending that i just cannot do.
lying to Idrune about Talitha doesn't sound like it should work but I'm willing to give it a try.
the room i was talking about is in the Lizargon village side of the map. go south from that spot you can find Naipei in on the Lizargon village side of the map to help her kill red Lizargons every few days in exchange for resources, you can actually collect more wine this way if you roll lucky after the battle. the room I'm talking about is in that group of ruins where the maze temple is(the dungeon where you have to walk in specific patterns in some of the rooms in order to unlock a door)
escaping with Tulip requires max affection with her, mentoring Galan, and watching all sex scenes associated with Tulip and Galan minus the one involving the Dwarven Dress.
the only major bug i have encountered kinda makes me unsurprised that another bug that blocks an ending exists.
Easy Mode has two major bugs, technically three but two are the same bug just in different places.
the first one is that once all boat escape objectives are complete, it stops displaying the "X days left" counter.
the second, and by extension the third and more game crippling, bug is that attempting to watch Idrune and Talitha's second sex scenes will result in a game freeze on the black screen once the dialogue ends following confirmation but before the game can display the text setting up the scene before going to the image of the sex scene. the game would also flash up the camp location indicator before going completely black.
I have seen a game crashing bug occur in Normal mode in that optional battle you can fight alongside Naipei against red lizargons, which occurs when Naipei tries to make an action at the end of the turn but has nothing to target due to the lizargons being killed before she could attack.
now if you're attempting to do the ending in Easy Mode then it may be that event flag bug I encountered may also apply to trying to achieve Tulip's escape ending.
this game seems to have moods regarding when it actually flags events. and with the creator pretty much all but stated he no longer wishes to update it, its unlikely to get fixed
