Tried several times and barely pass the "3-shark tunnel".
Since you have high score recorded, maybe it's a good idea to make it easier? Or at least the first few minute imo.
The highscore is your best time and I did not want to make the game too easy cause this ist the only level, so the one level should be a Challenge. But thanks for the feedback i will try to make it Bit easier next time.
Just find out I type "minute" instead of "second"... Thanks for replying, good to know your thought :)
