great game and fitting game concept!
It would be better when the game area for the player who won will reduce, rather than increase, because otherwise its even harder for the player who is loosing to win the next round.
A downloadable game
Use your speed and strength to beat the other challenger and become true owner of the one spear!
Throw your spear to kill your opponent or gain power. For each time you kill your opponent, the wall will close in on him. Once a challenger has taken over the whole arena, the game is won.
For the uploaded build you will need 2 controllers and 2 players BUT there is an optional build here in which you are up against an AI and have the option to use keyboard + mouse instead of a controller.
