You've got something that could be really nice there, but the main problem is the lack of goal outside of surviving (i'm deeply sorry if there's one, but i didn't understood it)
Other things that you could improve too :
- just get rid of the handle on the slider, it could feel better without it
- make it so the more cracks you have, the more you lose water
- reduce the blue part, it takes way too much space on the screen

Now on the good things :
-The movements are really good and satisfying ! They make you feel free
- The trail is a really, really good thing, thanks to him you can see where you're going without feeling offset, and it just looks cool

It's a funny game you've got here, but could be a lot better with just little improvements. Good job there!
