Amazing for about 10 minutes, then requires $$$

Concept, graphics and gameplay are excellent. However, the free characters get stale quickly and the cost to add new characters is obscene (note they seem to be giving away Captain America for free at the moment). This is a game for my iPhone, not my PlayStation or Xbox, Im not spending $20-$30 on it. Provide a way to earn new characters through gameplay, make the characters $0.50 or just sell the whole game for $5 and be done with it.
