Protip: If you take more than 60 minutes to complete the level, Survival mode initiates automatically, whether you've completely dominated the level or not.
The only issue I'm finding is the annoyingly frequent occurance of sticky keys, which will basically force you against a wall and not let you move anywhere else until you pause the game for 3-5 seconds.
The game glitches when you enter situations where you must hide behind walls: Holding down the spacebar causes to player to get overloaded, and you begin lagging, potentially killing you and decreasing your accuracy dramatically. Perhaps this contributes to the second least awarded badge on Kongregate?
I'm finding that holding the space bar will cause your shots to lag after a long while. Your movements will be delayed, firing is delayed, Hell, even releasing spacebar and hiding again is delayed.
Our computer is 1-2 years old, so I am getting so much lag that I can move and semi-aim. Even so, the number one reason I die is because the game is lagging, even on low quality. Add an option to remove some of the ground decoration to reduce lag.
Needs to be an impossible badge; the game relies too much on luck to give it a hard badge, which requires a lot of skill. Impossible badges require pure luck to earn.
Beautiful game. Relaxing music, interesting scoring system so you can be slightly competitive as you play. @ the haters who say it's boring: You should just go play another game then. Just because this isn't the blood and gore you are used to does not make it any less better than the best games on the site.
