    Controls seem a bit sluggish, but it's a very nice concept and well executed.

    Interesting concept but, I find it really hard to play. I'm struggling to control the turret thingy.

    Had problems with the controls on the Original file on Kongregate. I have fixed it. There are power ups that make the gameplay easier as you go on. They are random so the gameplay changes quite dramatically for each time you play.

    I liked the concept as well as the neat tron graphics but I found the game very hard to play.

    re acceleration:
    So the basic thing here is that it's good to have deceleration faster than acceleration, especially when acceleration is large (otherwise the player just loses control too quickly).
    The question then is how you do this, when the player's velocity is in a completely different (and arbitrary) direction to the force the player controller is applying.
    What you really want is:
    force = min_force + (magic formula that makes it 1 when it's in the opposite direction of the current velocity, but 0 when it's in the same direction) * extra_force

    That magic formula can be found using the dot product (http://www.euclideanspace.com/maths/algebra/vectors/index.htm - you might want to look at stuff on that page in general, it's a pretty good resource, you'll have to search for 'dot product' to find it there but it's there). You want to take vectors of your force and current velocity, get unit vectors of each of them (so they're both of length 1), and then do a dot product. You probably then need to do a ((result+1)/2) if memory serves me correctly.

    Sorry that's such a quick overview, hopefully that website fills in the gaps (feel free to ask if your head is spinning/something is unclear - just tweet me so I know to check the thread again).

    thanks pdyxs. I will try and get my head around this.

    I'm having great fun playing this. There's a nice groove to the controls, you have to think ahead just the right amount. Great style.
