the idea to kill zombies in top down is fun, but the level is closed or its just me >.< i couldn't open the door for the next part of level 1, i killed 2 zombies and that's it, i got stuck around in the first part (cant pass the walls), and make sure to add trigger once for the ammo sound effect :3
with a lil fixes around and effects, the game can shine :) ,overall well made :3
