I suggest adding a feer element to the mouse and maybe movement if you swipe over the reeds they sway and to make this a game add platforms to jump to and goals that the frogs go to I love the simulation but this can be so much more
I have completed the request at hand. It's just a bit strange when entering and exiting the water, but there you go. Enjoy! (I had to remove the scare frogs). Note that you have to click the left and right buttons to change the view to see more swamp. Thanks for the suggestions!
