Honestly not entirely sure if this game was a dream or not, but it's worth a try in this subreddit, I don't remember much about this game other than the cartoonish 2D gothic artstyle that had a lot of white, grayish and black tones, kind of reminiscent of Charlie Murder, I only remember playing a few minutes of what seemed like a demo for it from a game magazine CD (no idea what it was, but I'm pretty sure it was a polish one). I can't remember the gameplay loop for certain, but I remember there being a lot of enemies in the background, as well as some sort of castle/gothic building shown in the farthest place and you went through from the foreground into the background getting rid of the enemies. It had a strong feeling of depth, that's one thing I really remember about the presentation. I remember it being turn based and you could choose the next opponent, but I'm not 100% sure about it, that's pretty much all I know! Any ideas would be greatly appreciated :)
