Hey, thank you for rating our game :)
Our Record is over 50.000 but we only reached it once so your 27.000 are "average" to low average from our testing.
And second the Fireman have a mechanic that I forgot to mention in the tutorial. They have 2 timers when called one is a hard cooldown in which they cant be called and the second one is a "soft" cooldown where you can call the Fireman but they'll have those high death counts.
Hope I could clear thing up :)
