hard till the end
game is hella hard untill you get to the last level, im writing this review while playing. All you need is the first three upgrades and its the end of the difficulty. the game is really good though, kept me coming back to play till the end to try and beat it. There is a glitch though, at the last level after you kill so many the gun fire sound goes away and you no longer hear it but you can still hear all the other sounds. Also, the random spawn on easy needs tunned a bit because at some points you will die no matter what you do. one other thing as well the names of damange and power need changed or a tip window needs to be added to tell the differences because i think people are getting confused by the names. Other than that its great. Its time to die now because im getting tired. GG
P.S. Another glitch i found. If you restart and lose the sound at the last level, any zombies on the screen stay on the screen and are killable when you restart.
