Maybe we could have a separate area (in the same way Lockdown is separate.) where we have a limited amount of something, with which to do something. Examples:
-Limited weapon swings/shots/charges with which to clear an arena.
-Limited time with which to get through a twisting C.W. tunnel path jammed with rocks and ghost blocks, using a gun.
-A single bomb explosion, with which to destroy a difficult configuration of bushes.
Any thoughts on having puzzle modes, or ideas for limitations/goals?
I highly doubt the ability of Spiral Knights to be used as a puzzle game, considering its grid layout, the limitations are too much. There are already much puzzle games with grid layouts on the market, so I don't see the need for this.
