I liked the 3D models of both the orcs and the character/companion. I felt like 100 orcs were too much, and sometimes the waves were just coming without any change in challenge. The mouse was exiting the game frequently, so I had some problems with it during the gameplay.
Also, I encountered a bug when entering the leaderboard: it popped up an HTML error in my browser, and the game was unable to accept my inputs.
Nice game and and solid entry! Congratulations (Nice to see a 3D game with leaderboard and combat mechanics done in 1 week)
