"Not very great" is right. Sort of. Very little of it makes sense, and there are a vast number of things that need to be improved. Zero in-game instruction, and it isn't clear in the description how to control the game (each time you switch from moving one way to another, you fire a bullet). I don't know how "syncing" to the soundtrack applies. 1/5
So, here I am, enjoying the game, right? Putting up walls of Rocket Turrets, watching silly Heroes melt before my explosive might. Go to the next level and read about the new twist, thinking "Oh, psh, my rockets can handle anything!" Well. Beam Blaster? Destroys rockets? Rip my heart out, why don't you, Nerdook. :C
...Why didn't I just bust the robots up and take the girl back? I mean, I have a heavily armoured gyrocopter, armed to the teeth with advanced weaponry, a computer targeted, laser sighter Gatling gun, and a cat. I could have used that money...
I know it's a minor thing, but I'm slightly annoyed with the problems with the Mute SFX button. Not only does it not carry over from map to map like Mute Music does, it doesn't even mute all sound effects.
There is a glitch I noticed when doing the Enforcer quest, that I thought was handy at first. On the mission where you have to deliver a package and all events are enemies that auto-attack, you can sometimes skip the next battle. Unfortunately, this also caused the game to freeze on me; the enemy is trying to attack, but I'm not in the battle screen and have no options.
