Once again - going slower than I'd like, but I'm aiming to finish and have a basic playable thing by Monday, so I can worry about the bugfixing and extra smaller things Tuesday night.
Main two things I added were Medal times you can aim for, as well as a "water jet boost" bar. As you release the acceleration, your boost charges so the next time you press it, it's a instant boost of speed. It's actually fun to get used to trying to shoot around the track well, but I definitely need to add in the collision if I want to make it actually useful...
I did also add the diving to this, but there's not really anything to test it on just yet, so eventually!
