Maybe Make The Bullets Collide With The Object and Give It A Sound, And Make The Zombies Collidable, The Square Needs Something On It To Make The Direction Easier To See. Maybe Cut the Squares And Make It Something You Can Customise so You Can Make Different Zombies. Forget Levels And Make It Survival with Days And A Arena That Has Interactable Objects Such As Sandbags And Bricks, Cover. The Bullets Are A Bit Off Accuracy. Nothing More To Say Except Upgrades. I don't Rate Unfinished Games But Work On This Definitely.
I Love How You've Taken One Big (Risky) Leap From a Survival In One Room Surviving Waves To Going Outside and Exploring The City, And Actually Meeting And Talking To The Survivors. Its Also Realistic, Trying To Conserve Bullets And Food. Awesome Story Line and Twists, The Government Is Evil, I Didn't See That Coming ;) 5/5
