; this is a painful one
; mostly because the tree puzzle is sort of obscure in the original
2020-07-14 03:53:08 +00:00
; in original you get a match, then light it
; the match will flicker and burn out if you go outside
; light the pilot, it will turn red
; boiler PSI starts at zero
; turn once clockwise, fire starts, nothing else?
; turn once counter-clockwise fire turns off
; turn twice CW -> ?
; turn 3 CW -> ?
; turn 4, 5, 6, 7, 8, 9, 10, 11, 12, CW -> ?
; can turn up to 25
; at 12 starts gradually going up
; (needle swings hits end, waits like 5s, goes up)
2020-07-16 03:52:50 +00:00
