For certain you are right, but mind two things. First, from what I have heard, developers sometimes loose measure of how good they get at playing their game, expecting comparable level of skill from the players. This ought to be a small game, right? Other thing, is the patience.
But I guess that I may not properly understand how roguelike games are meant to be. For the shift+click, I did not know, but perhaps it is maybe too obscure, then? Why not make it more transparent, easier to spot? Still, the case is accessibility.
