WASD to move, space to jump, E to throw a grenade and left click to shoot.
v1.1: I added jumping! Now you can easily avoid the zombies while reloading. I also added a color feature from one of my games, and made the character say your username. (the game is at https://scratch.mit.edu/projects/663494568/) v1.2: I updated the grenade's sprite and how the explosion looks. Instead of just appearing and disappearing, the explosion gets bigger and bigger until it disappears. I also added a medkit to heal yourself, but it won't heal you over max health.
