Not saying that it's not allowed to have two projects being developed but I have worries as now Keepherdev has two projects in ALPHA stage and also has to keep up with expectations of updates on both of them.

I'm not a programmer or developed a game myself so I'm no expert on the process of building a game but I have seen many projects die from situations like this from other developers. Wouldn't it be a possibility to of implemented this into Dungeon: Keep Her to of kept it as one project and just a different mode to expand gameplay?

Im guessing its because they wanted to develop a new gameplay style, but want to use what they made in DKH.
So basically its like trying to learn what they did on their current development, and then try build on it on the other at the same time to maybe spark new ideas.

But i totaly get what you saying, because  if i was going to make something i would probably just stick to one thing first, then work on something new when its done.
