Good Point
[+] Is playable
[+] Seem like gladiator arena
Bad Point
[-] Damage too low, should increase it a bit more
[-] Victory condition seem awkward, instead of victory after defeating the opponent. It show defeat. (Consider this as bug)
[-] Map is protected but never mention
[-] Should had describe it as attack = left arrow button and defence = right arrow button because people might had mistaken it as mouse left click and right click
[-] Instead of 2 player only, it would be much better if playable by at least 5-8 player.
[-]Kind bored if try to play for second time.
Overall - 2/5
Comment : Acceptable, but should add more feature to make it interesting and remove the bug at the victory condition.
