There really should be a draw button. imagine this situation:
Ashi v Helene, full health and energy, but both are far away. Whoever moves closer loses because in the end, they're not going to have enough energy.
I acutally really like this game 5/5. when I first heard of it, I thought it would be some generic magic game.
I think that more than one character should be allowed to battle at the same time, and the health bar needs to be labeled clearer.
