My doctor would not approve of the anxiety your game gave me and what it probably does to my blood pressure, lol! I love the creativity here. There's a sense of panic whenever I see that bar fill and wonder what's coming next, but a good panic.
The company is not liable for any health issues, sorry! You can take it up with HR, but probably shouldn't.
On a more serious note: sense of panic was exactly what I was going for, so I'm happy (?) you got to experience that!
