Pressure

Hmmm... I think you need a better help file. It looked interesting, but I just couldn't work out what I was supposed to be doing!

That's the fear part, being unsure and a timer that's going down

No that's not the fear part. That's the confusion part. Is there water rushing in? We don't know. But that would be the fear part.

After I figured out what was going on, the game was almost enjoyable. I think a bit more guidance and a less strict time limit would have made it better.

The time limit is around 50 seconds more than the near-perfect run, I've done quite a lot of tests to balance it
