Hey thanks loving my game, this really made my day :D For the water btw, its just some simple circle colliders with Unity's rigidbody component on it, also a slippery physical material is applied on it. And when you have a lot of tiny slippery circles, they moves like water (just imagine throwing marbles in the sink). Also you gotta apply a shader to make it looks good. I also made those circles just float on the surface so that the amount of circles can be reduced (improving performance). Hope these can help ya :D
