like real talk 1800e per run is quite a steep price for some of the more difficult content this game has to offer,
not even including the implied cost incurred via having to spark in it due to the currently increased difficulty.
it would be nice to be able to do solo SL runs at 450e, though i'm not sure myself on how i'd implement that.
maybe have the elevator take either shadow keys, or having people deposit 450e into it, locking the party
when someone deposits energy, and it opens up when everyone in the party has done it.
this idea is great
