Meh... It was fun for a little bit
It was a fun game at the start - it gave the feeling of being overwhelmed by zombies and the like. I enjoyed the single bullet reload at the start - it made it more difficult but later on it got a little tedious to keep clicking... You also said you made it harder I just stopped at 7:30 and watched as the zombies overran the bed.
Suggestions: More guns, more zombies, maybe tasks you can set your two friends on like - build another trap or make a better barricade or something because they just sat there after you used their idea and you really couldnt come up with something innovative and unique per game. For instance maybe its broken into rounds and after each round you might have materials that you combine into makeshift tools or something. And please put an ending into it.
Graphics - The graphics were decent, enjoyed the spurting blood and "headshots" and such. You had damage based on position which I liked.
Style - It was another zombie shooter game but it had its own unique touches which i liked
Sound - Sound got annoying fast. The gunshot was fine but the background music was kinda annoying.
Violence - Blood spurting, innards eating? Yeah it was alright.
Interactivity - You have four actions. Shoot. Reload. Drop a trap. Drop a bed.
Humor - I like the laundry trap
Overall - Innovative idea could use a little work.
