Let's be a good sprite mask user and set a custom range, shall we? :)

Make the mash button fill the bar up more per press the longer the hatch remains open.

Set default colourblind mode state based on KMColorblindMode instead of always being on (this was intended to be the case previously but I set it too early).
Make the siren red in the final phase so that it matches with the manual.

Initial upload!
