Like everyone else is saying, it could use a leveling system or upgrade system. Things such as making your character run faster, or perhaps an upgrade of the weapon? Certainly a fine work still. A save point is something else to take in mind.
I understand that everyone love upgrades. BUT : try to consider that all the game interest is about mastering your OWN skill. If we add upgrade, the game would just be non-sens. Please, also consider that checkpoint in a Survival game would be non-sens as well :)
Wow I cannot believe you made a unique version of a game like this. It certainly has it own touches which I find to my liking. Thanks for letting us customize controls, I find it rather bothersome to use the default keys. I can certainly take a liking to this. 5/5 for sure. You deserve it SoulGames.
Keyboard is way easier to control and direct. If you find mouse annoying, try switching to keyboard screen. While I'm at it I suggest an upgrade for your soldiers' health.
As almost every other poster said. This game is actually very entertaining! It isn't hard to where it is frustrating and you can get a good few minutes to waste on it. 5/5.
I just simply love the uniqueness of this game! The way of upgrading, the way you can contribute skill points after leveling. Cannot believe this game came out in 2008! There are none that compares. 5/5.
No thanks, this game is a shit and deserves a 1/5 rating :P
