slight bug: it is possible (though quite difficult) to get the Air Tank before getting Sis. (i thought it was just another hidden thing!) the jump to the last plate is tough but barely doable (tough because you are very likely to burn up)
Fun game - awesome story! The backdrop for the puzzles is just perfect. 5/5
(however, a note: spriklers and foam extinguishers wouldn't help against thermite - the water would vaporise and thermite doesn't need an external supply of oxygen; liquid nitrogen would be better to rapidly cool the metal. people would still benefit from the alarm system, of course.)
