Constructive criticism is good for the soul, I think:

• The timer is just too short.
• The constant flashing, to me, is more distracting than atmospheric.
• The "How To Play" section never really explains what "Add Fire" and "Add Water" do, specifically. So I'll get a number like 5 and click "Add Water", and it'll just say "WRONG". Why is it wrong?
• I felt like having to gamble to gain additional time was not the best way to give the player additional time.
