Can you reorder your heroes in the list? For example, I'd like my high-armor warrior to be the first one to take damage so that I can heal him with my Paladin.
Cool idea, but I really wish there were more levels and maybe a new mechanic or two. What if there were one or two moves that you unlock after completing the first set of puzzles? Things like a special piece you place that pushes away all of the squares around it, or increases the pushing power of a blob of squares you click.
The central appeal of this game is its aesthetic, and I think you could probably squeeze another mechanic or two out of this one.
Otherwise, fun game!
Cool idea. I don't like how early many of the obstacles are in the levels. I felt like if I failed once I was immediately back at the start and had less than a second to dodge the first obstacle.
