There was no ammo at the start of the game and clicking the 'shop' buttons doesn't work... The top right corner did change to 1 and then 2 but that's pretty much it...
Oh, okay, I see. Basically, the top right corner is how much plants you discovered. You get it by swimming into every new plant. For that you can buy items in the shop by swimming into the item that you want. Guess I need to make clearer instructions on how to play the game
