Man the steps on this are strict. In some spots like just before the large cannisters, one wrong move can doom a run. (On one run I didn’t realize you couldn’t use the large cannister more than once and that did me in.)
I wonder if the main timer is even necessary. Like, early it causes you to rush a bit, but it’s quite a trial and error game, and the steps are so vital that the timer ceases to be an object, and once you collect the mask, basically all the pressure is off.
Unless you get trapped in a doorway as it closes. Which I did. >.>
But very engaging overall. Great work!
