I have an idea that would make spiral knights even more exciting, Jetpacks! With jetpacks, you will be able to battle multiple floors all in one level. Each level is made out of many sections to explore. That means, even more crowns, heat, and even treasure! It can make PVP even harder or more fun.
Also, the benifits of having jetpacks is to fly over monsters, but jetpacks CAN'T fly over obstacles they have to overcome it themselves.
Every jetpack also has a fuel limit. Each jetpack can hold up to 1000 fuel units. If they lose all the fuel units. They cannot fly. Each bundle (1000 fuel units) will have a price. 5000 crowns. It might sound outragous but it sounds great if you want 2x more treasure.
But wouldn't it also be like a "jump" command? o_o
