Things I liked:
The gameplay:
Movement and gunplay was easy to understand.
The artstyle:
The assets you chose worked well.
The sound design:
The sounds you chose set the perfect tone.
Things I disliked:
No objectives:
Unfortunately, once the fun of blasting zombies wears off, there isn't anything to do. Adding a larger map and objectives like refueling the car would really help the game's longevity.
Zombie behavior:
Having the zombies spawn in on screen was a strange choice, I think it'd be better to have them spawn in out of sight. There were times I took damage because one spawned in right next to me. Some zombies also got stuck in the wall.
Things you could do to improve the game:
Add missions:
Adding an extraction-style mission structure would really fit this game well.
Synopsis:
A fun little zombie blaster, with a lot of potential for a full game.
Thanks for your entry. :)
