By the big tree there is an upwards path, if you are around level 4 or 5 you are strong enough to take that path. At the end of the path there is a rope which you can use to climb down the well. You haven't finished the tutorial yet.
I have been thinking about the UI-selection, I will most likely make it less transparent and change the color. The ladders are truly fucked, I will fix it but since it cant fuck up progress at the moment it will be later.
This is an rpgmaker game, will think about your other feedback!
If you cant be bothered to finish it, though I recommend it because the real good stuff comes later, you can watch it in its entirety here or skip forward a bit and see if it might be worth your time after all:
There is an "end" to the demo at a good point in the story. You could also use the video if you get stuck to see what to do. Thanks for playing, and for the feedback!
