Very strange game. I played it for about an hour. What I got is that it is some kind of frogger (sealer in this case haha). I colect coins to buy stuff after the level, and the blue thingies make me faster, so that I can avoid the sharks better. But what do the colored rows of tiles in the ground do? They get grey, and red. I could not figure that out. I think they had something to do with the shark spawning?
Managed to get two sharks, but died, then everything resets. I guess I would have to catch at least 5 to trade at the Town Hall? But then if I die, would that reset?
Game is very interesting, and quite fun. But also very hard. I coudn't understand if there is some kind of progression (maybe with the sharks), but I guess not.
