I'm happy to hear it! I'm still touching up the visuals, and, when I've added more variety to the background art with lore implements and higher quality details, it will look much better. But vibe and aesthetic appeal are definitely an important aspect to this game and the series of games I plan to spawn from it.
Music is the next thing on the list actually! I will be implementing a bit of music in the coming days as soon as I've gotten it set up. I appreciate your input!
Yes this game will have many unique synonyms of dark. I hope to stay away from naming everything "Shadow ___" or "Dark ___" as much as possible. So, if you decide to check in every once in a while, you'll be seeing many examples of fancy words that mean dark in some way or another.
