Many thanks for playing our game. We're sorry you fell foul of the stacked flares and dropping them in the dark. We've fixed this for our post-jam update, coming out on Saturday. We no longer stack flares and we're adding an emissive texture to the them so you can see them in the dark! Good call on the PgUp/PgDn, other people mentioned the same thing. We're moving those to the R/F keys. We're looking forward to playing your game soon.
