1. No routes yet only a couple of ntr scenes
2. U need to buy it at the gift shop (west of the elf town) for the bunny suit and im pretty sure u need to finish the quest to rescue the elf queen first
Both have the same answer: the memory Cg room, inside u gain access to the gallery and there are also 2 buttons, one gives xp and the other gold
the Cg room can be accessed from your beds (Nitt's house, the tent at the elven town and chilist's manor) maybe im forgetting a few
1. In this thread there is a walkthrough its not up to date but it covers this part im pretty sure and some other stuff for later
2. translator++, yandex or some other mtl could help you and i think there is an english patch in this thread that translates extra stuff
3. here is what i recall for the quest, i could be missing stuff but
-u need to ask NPCs about the mayor in a certain order im pretty sure most if not all are in coast town but there could be a few in sunshine town,they tell you anyway to talk to X and X tells you to talk to Y, etc. the last Npc is the smuggler (south west house in coast town), and she opens a secret door in her house (she might give u a small quest before that? i forgot) anyway, you go to the secret underground, the mayor is her u can talk to her and one of the goblin with her will give you a small quest, once its done the mayor will talk to you and u can go back to sunshine town, for the miners, there are 3 of them i think, one wants a beer, another some food i think and i forgot the last one, once all is done u can go talk go Polina in her house she asks you to put some stuff on 3 signs in town then u go back to her and she tells you to go sleep or some shit then the quest is done and the mines are open
