Just got a beta key and first I have to say already I am really enjoying the game without any bugs or problems. Only suggestions so far are 1. I think it would be better if lava pool and acid pool caused automatic damage if a character moves over them. 2. It would be nice if the word box on the top left corner could be closed optionally as in some levels ie. Against the cockroaches level 2 it gets in the way.
Hmm, I thought any self respecting character would jump over said tile. Walls stop people from moving to a particular spot. If terrain attachments also did damage to walking over them as well as being common and painful, they would be overpowered.
Just to add to the original post, if these items lava pool and acid pool did automatic damage to characters then to balance them the damage would have to be reduced for example 5 damage for lava pool and 2 damage for acid pool (still lose armour) . If this was done these could be used to block passage which they cannot do at the moment. The only way to use these spells at the moment is hope that the other characters do not have move cards then play them.
Acid spray pretty much blocks passages currently. I mostly use it as movement blocking. Any damage is just a bonus.
