my first try i used common scence and looked around the screen i saw upgrade and saw a ship in the open so i clicked on the upgrade and hoped to find something to do with ships. i found the docking things and just upgraded the number and from there it was sort of easy.....
i saw your next one it looks good i was sort of disapointed that you controll cause its fun to see them run around but o well im not the maker you are but you have improved it and i cant wait (plz message me madfred1@hotmail.co.uk :D
not to say ina bad way but i hope the next one has some effort i mean this one now only has wandering ppl and zombies with music its not really a big thing in all
it doesnt really matter if u make the map animated or something but try and make it to look real in the future i dont mean like some things where its just bundled up and looks like a cartoon
you could also do some sort of civilian events where some come in? or maybe some sort of stronger zombie that can take more shots than a normal zombie? sorry for the long comments but you could turn this into the greatest zombie game ever
my idea is you add ambulances police swat etc.... but like an army that responds to HUGE infection now lets say u have a setting where u can do 1 random human infected every 30 secs? or someing i mean then you dont have to restart the game ^^
