I know you literally don't care about what I have to say because it isn't YES SIR MAY I HAVE ANOTHER PRIZE BOX but I very much enjoy Spiral Knights and would like to suggest that you continue developing the game. I enjoy what you have produced and would like more of it. I don't really know what else to say to make you listen and actually consider doing something. It's frustrating.
As far as I've been informed, they're trying to milk money out of SK to further develop/support Puzzle Pirates.
It's sad, really. Puzzle Pirates apparently is more important than SK. I don't know what that says about either games.
So yeah, the chance of them actually developing this game any further, releasing new weapons (not just reskins for promo boxes), ever stop (re)releasing promo box sets or ever finishing the story is, pretty slim, to say the least.
