I REALLY love the highscore idea. Definetively one of my most favourite ideas of how to use this limitation. The game looks just awesome. This is a super job! Interesting was the concept that I had to switch my thinking about who jumps first. That totally broke me, but was super cool.
At first I thought, why that water spawning is so angry about me, but than, as I red the highscore rules, i knew why it was designed that way.
Just great, congratulations.
