Lockstep80, 'a quantum leap' is an idiom meaning: An abrupt change or step, especially in method, information, or knowledge. So in fact, they promote their game like: "Hey, we did something different and unexpected to add appeal to the game. Play our game!"
The last power orb was for if you completed the planetary traveling device in a different order. Each planet needed a power orb to get to the next planet, so an extra one was added in case you decided to open one planet over the other.
A few things I noticed were that when you tried to scroll up with the mouse, to see more in the chat, it also scrolls up your window. Another thing I noticed was that some of the kommands are screwed up. (Heh, bad joke). Yell works, but shout doesn't, neither does whisper. Other than that, I think it is pretty good. I even made a room, Walrus Palooza, although I worry the amount of rooms might cause a bit of lag, maybe only have a few people be able to create permanent rooms and have all the other rooms only temporary and be destroyed once the owner logs off.
Game is all right, needs WASD controls. Currently to play this game effectively you need to be left-handed. This game also needs different ability hot keys, right now, I have to either take vital time to stop moving and press it, or stop shooting and press it, since this game is supposed to be a run-n'-gun with a little bit of strategy involved, it would be in your best interest to maybe make it so you can use ZXC for the abilities. I also think you should go about increasing the art quality, which right now, is all right, but can still be improved. The background makes the enemies blend in, (at least with my eyesight, it is really poor). Overall, a 3/5 right now, if you make these improvements, I'll give it a 4/5.
It just displays the usual 'To use this you need the Greasemonkey Script.', with the same chat as it normally is. When I right-click the Greasemonkey icon, it isn't displayed on the list of scripts for this page.
