Sorry, but it's bad on so many levels.
Let's start with design, really poorly made, looks like he is shooting with a tube in a middle of
a swamp at god knows what.
Gameplay, consists of basically just grinding score with not much of an idea, zombies
spawn so randomly that most of the time they might just spawn on you, so what you just have to
do is stand in one corner were you can disappear for forever and your good, you can get your
desired high score. You only have one weapon that seem to be capable on firing only one bullet
and if you shoot the second bullet too soon the first one just disappears. Hit box is way too large.
Zombies do have different appearance but they seem to deal and take damage equally.
At some restarts there will be horde of 100 zombies the other maybe 10 or so.
Increasingly large lag after 400 or so kills. Medals don't work properly just got 500 but no medal.
And I think that might be all, I am sorry, but I am just stating what is in the actual game.
No offense, but this is not a good game.
