For some reason in this game jumping sideways is super fast. Tried out with a friend who sprinted forward and i jumped sideways, approx 10-15% faster to mash jump and go sideways (has to be hard sideways).

Thanks for sharing! I have noticed that as well. Jump spamming forwards is also faster than just running forwards, but sideways hopping is faster still.

Upon trying it more i noticed you can even sidejump on top of water to move faster than swimming.

I'm not sure that is correct, at least not in deeper water that you can swim in. I couldn't get it to work :)
