We are developing a type of horde survival game set in a fantasy universe, where the player must hire and heal his companions to survive against waves of ruthless opponents. They must manage their "life force" throughout the game and can win by exchanging some of their maximum life for permanent boosts to their soldiers (e.g. Warrior, Archer, Mage and Rogue class options), can gain some life back after a successful stage or take risks to travel to the ends of the "gladiator-like arena" to collect health power-ups. There are a variety of enemy types which have specific behaviours (much like how each soldier class type does) and may be stronger or weaker against certain damage types. The game will combine skill, tactics, preparation and careful health resource management to win, while teaching important "life" lessons (such as teamwork and a balanced composition are necessary for success in life) :)
