Take the depth of Dwarf Fortress, add a bunch of lazy mages and update the interface to modern standards? That's Mage Tower in a nutshell. We're building something really ambitious - a world that you can build to your own whim, while carefully balancing resources, knowledge, and external threats.
Three months since the last update and not even a blog post in the meantime? It's misleading to keep selling this as an alpha when it's clearly been abandoned, as its certainly not worth the asking price in its current state and that seems to be all you're getting.
I know development takes time but once you start charging for your alpha, you have a responsibility to communicate with your players occasionally.
