Argh
I absolutely love this game, but I had to give you only 6 stars because I hate it so much.
Why is that you ask? Not because it was incredibly difficult, even on early stages. Rather, it was for two reasons. First, when I die and reload, I have to place all my mines over again. And I died a lot.
That brings me to the second reason. Although I died some times legitimately, 75% of the time I died because my goddang turret WOULDN'T FIRE, even when I clicked the mouse button. I would be shooting at someone, my energy would be near full, and I would stop so I could turn faster, and I'd try shooting again, and it wouldn't fire. Then the bomb enemy or whatever would get to me and kill me instantly.
This is such a fun game, but BECAUSE of that this type of bug angers me profusely. It was irritating to get down to 5 seconds left on the clock with 3 nuclear trucks left on screen, try to shoot them, and have nothing come out of my turret and die. Then all the mines that I previously placed (and saved data after doing so) were gone and I had to replace all of them.
Another bug that annoyed me is that even if I shot an enemy enough to kill it, it would stay alive for a second, and then die (without me shooting it any more). This combined with the bug mentioned above was hell for those situations where a suicide enemy is right next to you about to hit you. I'd just barely get the hit in, but I'd die anyways.
I know you made this game over a year ago, but I'd love a fixed version, if you ever get bored enough to do so.
