This is a nice game!, its quite cleverly designed too which you'll figure out if you actually give it a try you'll find there's more to it than just surface appearances, its tactical and smart, its more intelligent than my brain because i find myself completely NOOBIFIED when it comes to a neat learning curve thats not annoying at all because it's FUN to figure out what you could be doing better here and there... always a better way forward 😁🫶 great game so far (RATING 9 out of 10! - 92%) āœØšŸ–¤āœØ

It's a weird game- it took me a game or two to get it, but once it clicks, it clicks. And at first, you find it easy, but the difficulty tiers *drastically* increase the mastery required by the player, until it reaches the point that you have to have a basic knowledge of all creatures and possible events in the back of your head. Wonderful game, would advise.
