What would happen if you take the Minecraft world and throw in every Super-Awesome-Cool Stuff, that I can think of! That's probably what the developer of this game must've thought.
I suppose you could create stuff in the game similar like in Minecraft but everything here just feels off. Obviously all the NPC's, dragons, other creatures... which are higher res, simply do not fit in the world. Besides that, the UI feels and probably IS like a casual game.
Block Story has been in Early Access for almost a year now and there are almost no updates. It seems to me like this game is build in a hurry just to earn a quick buck, obviously without any love for games.
After reading some of the other reviews I found out there's also (going to be?) microtransactions, which is just silly for a game like this, especially since the game is still 10 bucks, which is way too expensive. If you want a game like this, go get Minecraft for the same price.
