The Idea is good but not developed enough
I liked the idea but you could have used a different animal to swim around in the ground or maybe changed the scene to a beach or lake , where a shark would might actually be. I found the controls difficult to handle and the game for me went to quickly
But the idea of the shark not swimming in ground is half the fun! The game isn't really developed because it was kind of made on a whim. It doesn't really deserve more then what you gave it, though.
Meh its bleh
explain me this. Why is their a shark swimming in the soil? You could have put in a point system and the player gets extra points for combos
