Good idea in principle but this could have been much better. With the auto attacking and slow firing speed I didn't have much control over the combat and could only move and aim. The random upgrades are maybe too random, eventually I got "Grenades lvl 1" which was the only useful upgrade but without any control they weren't that useful. The mouse could also set a throwing distance instead of only a direction.
The two choices after each round were sometimes identical and I have no idea what they really impact. What I don't pick turns into zombies, so what? What type of enemy is what type of civilian? Maybe I missed visual hints for that. Some had some kind of blue ring which was some kind of shield I think.
Basically more control over the combat and more explanations would have made this much better. There is a solid foundation.
At the start it took a while for zombies to appear and I though the game was just broken. There were several lag spikes when it loaded assets like music.
We both went for a survivor like "defend the villagers" type of game.
