I like the idea and the voiceover is great.

The water texture is good but it gets hard to look at when you go fast. Maybe you could smooth the colors a bit if you go faster.

Some collectables or the traveled distance would be nice to have as another way of scoring points instead of only having the platforms.

Good job, thanks for making it.

Here something that you can improve:
- For the boat try using Interpolation so you avoid the stuttering(?) of the boat
- Create a menu or some UI
- Reset the score once you lose
- Reduce the time you gain for each platform you touch (it become endless.
- Tutorial (i push every single key to understand what to do)

I really like the voiceover
