oh, yeah, the dialogue being in English is a definite weakness of the game. not sure the best thing to do about that. maybe i could add a non-English mode that simply makes the dialogue optional...
if you did stop at the first night--that is not the end! the end is the fourth night. in each night, you must go through all the dialog, and then sleep on the hay at the bottom center of the level (with the X button).
i haven't been able to figure out exactly which level you're referring to in your point (1). but yeah, on mobile the levels are all hard. i play tested up through the third night without any skips but they were definitely harder than normal.
thanks for playing!
