After our brainstorming session last weekend, we got in our first full day of work today!
Here are some mock-ups! Enemies will advance from the right, and engage whatever hero they run into first. Heroes will fight them by default, but you can also select your hero to use a special power. The meat of the game is sliding your heroes around in the 8 available spaces so that they are in the best strategic position against the approaching enemies at all times.
