I very liked the visuals. The gameplay was very confusing to me. You're ghost after 2 min of random wandering you meet weird dogs which can dig ground?? I feel like I'm missing something very important, game isn't very clear what are you supposed to do. I can destroy random ground tiles, and I cannot find anything in them. Then I switched to another dog just to get lost in the dark, it was very very confusing.
Try defining clear goals, that's very important for games , especially for puzzle games where you know what is the goal but the real problem is the reaching it, not finding it.
