not stolen
handel look at the credits... it is just hosted on that other site as well doesn't mean it is stolen credits clearly say programming: israel lazo
for the rest well fun game and all altough i had trouble in lvl 3 allready :p maybe cause i have a touchpad ^^ but then again the pistol has way to few bullets in it and it reloads slowly if you ask me :p and for the shotgun wel fun but can't keep to much bullets in it either.
my recomendations are: add turrets, more pistolrounds/clip (or faster reload of pistol)
for the rest i didn't found out anymore going to later on :p
grtz and fun game
