the really important thing is getting into Stage 6 with at least one or two bombs since I need those to help deal with the bulk of the turrets on the airship boss, if too many are left alive in the middle portion it gets messy from all the different patterns really really fast.
I really want to have resources for S7 too because the final boss is a bit spicy and I just want to carpet bomb it and finish the run
this game so far has been more challenging than XIIStag was
