Tried this out very briefly, but it just feels weirdly unfinished. There doesn't seem to be any story or motivation for me to do anything? A cold and mystery open is fine, but you have to do something with it. The environment and ambience don't signal to any mystery, just a run of the mill, poorly mapped generic adventure.
My best guess is that this is an early dev exercise? If so, that's understandable, and not a bad practice round. However, as a player looking to simply enjoy a game, this lacks a lot.
