I'm not a fan of the art in Bloodmoons at all. I will occasionally play a game with a similar type of cartoony art style, but it usually doesn't last long because such games tend to be very shallow. Whether or not that will be true with Bloodmoons, who knows? In any case, the gameplay isn't anything that I would enjoy from what they've said about it, and I don't have any interest in any kind of spinoff game anyhow. So I have no intention of ever trying that game even if it was free. Sorry, but it just isn't something I think will be a good game. I'm sure others will like it, but it isn't my kind of game, at least with the current description of the game.
If the game was completely new and in the 7D2D universe, it would be one thing. But right now, it's just a cookie cutter version of this with essentially a modded gameplay and a new art style. It looks more like an overhaul mod than a new game.
