So I had this idea recently about adding a completely new item class to the game, that item being booster extension. Its a pretty common concept in mecha genre games, but it seems like it would work particularly well for a game like spiral knights. Pretty much double tap a directional key and your character will enter a boost mode that drains a boost gauge, giving you increased movement speed for a brief period. For mouse only users, double clicking the left button on an area should give the same effect. The item class itself could give the game even more variety as some booster classes can have high speed but at the cost of a short boost gauge or even decrease your character's resistance to elements like fire. Some boosters can give a low speed increase but with a longer boost gauge. There are numerous possibilities. For the graphic designer, it is possible to make the characters more vibrant with booster backpacks but that isn't really necessary. To really implement this idea, all you need is some unique booster (flare like) animation to the back of the character while boosting, nothing special. Thanks for reading my idea in this long post, feel free to add your own ideas.
