I also just discovered that the water timer isn't showing the right time when [early spoilers] you're drilling into the fourth layer of the obelisk. When I died of thirst, it was showing 4.5s. Might be due to the fact that the water I was carrying wouldn't come off its cooldown until after I died? I love the addition, though, it's so convenient to have it there at a glance.
Anyway, I'm starting a fresh playthrough in the Steam demo version and enjoying it all over again. Thanks so much for all your hard work on this! :)
