I was thinking of maybe an obstacle course of some kind. This can have enemies out of reach that fire range/techs at you from an unreachable location (might be too complicated to create). Can have 1 hit KO traps to dodge or carefully move around and mission rank/reward based on completion time or something of the sorts.
Yes, unfortunately. Miss the community and hopefully we'll see a revival soon, but not likely. Would be really nice to have this up during quarantine. In the meantime, just entertaining myself with AOTI offline mode.
