What is Dwarves & Goblins?
Dwarves & Goblins is an endless beat-em-up type of game where you, a dwarf, battle goblins who are attacking your miners.
  • Kill the goblins by sending tremors down the ground using your different abilities.
  • Every move has it's own characteristics and each has very different uses.
  • Since you are sending tremors down the ground to kill the goblins, you are damaging the earth.
  • If the earth gets too damaged, you lose. If all your miners are dead, you lose.
  • Try to get as far as possible.

  • AI behind the miners and goblins
  • Abilities the user has at its disposal
  • The powerup system
  • The HUD / UI for the game
