I tried playing Cult Of Lamb on WASD and bought the game the same evening!
Now I have played for about 12 hours and here is what I think about it.
First, I really enjoy the art style of the game and the sound - they are just amazing!
Second, the game consists of two parts: rogue-like trips resembling The Binding of Isaac, and the base-building part. There are also a few small locations to travel to.
Despite the demo being focused mainly on the rogue-like part, for me it felt a little bit shallow. I used to play games like The Binding of Isaac, Enter the Gungeon and Undermine, and Cult Of Lamb rogue-like gameplay has so much less depth compared to them.
It is also too easy, and to not have it a mindless walk I had to use the maximum difficulty, but it got me to another problem: every time you die, you get a big decrease in your Followers' faith and you have to spend a lot of time in your base to get it back.
You actually spend most of your time building the base and preaching to your Followers. In my opinion, this process quickly gets repetitive, you have to do all the same stuff again and again or your followers will starve. It is really tedious sometimes. So eventually I found it a bit annoying and uninstalled the game.
So, my summary is:
It is a good game if you are more of a casual player who would rather enjoy spending time collecting berries from your farms and cleaning up poops on your base rather than fighting enemies. If you are a hardcore player and prefer it to be dynamic, Cult Of Lamb is probably not for you.
