Canceled by what, artillery?
I don't think it was ever OFFICIALLY canceled by the dev, no 100% confirmation right from the horse's mouth, but considering how long it's been since any update on the game... Generally safe to assume it's been abandoned by now, I'd say. There's certainly a
possibility of a return, but I wouldn't hold hope out for it.
Updates on ASIMOFU, since I'm not sure if anyone has done this lately:
Going from their twitter, apparently late last year ASIMOFU had a relative (or multiple? not sure, MTL is fucky) pass away. Took about a month for that, then in late January said something along the lines of "Now that we've taken a step back, it's time to get moving", though said "It takes a certain amount of determination to throw yourself into sexually explicit creation in this state of mind" after.
Afterwards, in August, they apparently got Covid which knocked them out for a bit.
As of last communication on Twitter, September 14th, they said "I made an impossible mistake and lost something very precious again". This could be referring to the game, or real life, not sure which.
