Gameplay ideas

New ideas 

• I'll keep the 'infinite mode' and add a small story mode
  • Story mode:

    
    

    • The player will go through 3-5 levels (using the waves' mechanics) and must destroy portals to stop the wave. Once it's done, there is a boss battle.
    • The story ends in a huge boss battle.
    • The player chose a starting region, which defines his starting hero (archer, barbarian, mage, to define...)
    • Maybe add different ending per hero
      
    • In some level, the player will be able to find a teammate, representing the Hero of the region, and add him to his team,
      • the same way it works in my other game (Five men squads)

• Shop is replaced with a skill tree
• Path will either give a new skill or improve a characteristic such as dmg, fire rate etc..
• Some skills are specific to a class (of course :D)
