These games are ok..
But its just... too lazy..
I mean, some red writing and a word that pops out...
Put some more effort in it!
About the weapons, they are just useless. The thing that matters is that you need to push SpaceBar. No matter what weapon you got.
You should really change it with some other effects...
The graphics? Good... but can you at least make a single Muzzle Flash? Or just a simple white screen for a quarter of second...?
The characters are like you drew them in 2 seconds.
I mean you see the real games on NG? Every single oject is an art there! Im not asking you to make an art out of this game, im just asking you to put some effort in it.
I dont want to say "it sucks" because it doesnt. It is cool and lame at the same time.
