This was a great game. The dynamic music ramping up as it got closer to the end was a very neat touch. Loved the voice, works very well for a short game like this where you're likely not gonna be repeating it enough for it to become annoying, and it does seem there were quite a few initial dialogue options. I actually managed to jump over the right-most dolphin by double dashing onto the tallest platform and then over. After that I kept running right 'till I fell into the void.
I'm not sure if there was any way to actually delay the inevitable, or whether it was just a case of surviving until the time ran out. Plus, the camera could probably have done with being made smoother, rather than making it rigidly follow the player (this demonstrates the concept, don't know if there's a tutorial out there for KGE) https://www.youtube.com/watch?v=Pd54vNc2N4E
