Please test my board. Tell me what you think and how many tries you needed to win. Edit: Try version 4
Won in one try, it was not hard but I did get very lucky with how the Imps and Trolls moved. One of my cats died at the very end by mighty bludgeon because I wasnt paying enough attention, but the rest won on full hp because of healing. Improvements: Add lower doodads and doodads outside the board. Add another Imp to make it harder. Take the AI's VP total down to about 2/3 so that the player cannot lose more than 1 character. Add some difficult terrain here: Spoiler: Difficult terrain in the red oval I was actually planning on suggesting MM scenarios to you after seeing your MP board designs but you beat me to here. Anyway, this is good for a first map. Even very good!
Realised a flaw. You could refrain from destroying the door to the outside and let your cats blast the trolls from inside. So i changed it so that if either of your imps die, you lose.
I had a few attempts at V3. I like the concept a lot, and playing as Psi Cats is fun. It took me a few tries, so the difficulty's there now. Thoughts: I think the map is a little too big, especially the house. I'd make the side furthest from the imps one line shorter. It would just cut down on rounds where I'm doing nothing but using move cards. I think the house could still use a couple more doodads, especially where the zombie room is. I agree with BVD about the difficult terrain. An unfortunate troll charge there at the moment and it's over, especially with the new loss condition. I like what you have so far, though. I don't want to seem dismissive. Does it have a story?
I deleted one line from the map. I changed the look to something more sinister. I did not add difficult terrain. When the trolls are coming near, you should run away. I have a story in mind.
