Thanks for playing the game. Sadly, we didn't have enough time to animate the player's attack; however, it should play a sound after the attack. I think it generally takes about three attacks to kill one of the zombies.
Ahhh I see! I didn't catch that. I think I tried once or twice in front of the ennemies but assumed it didn't do anything.
No worries it was a bit of an oversight on my end.
