I'm new to trying this, and I'm going to try and make a very basic and dull level for the sole purpose of easily being able to make animated gifs of the characters when I take screenshots. There for the background is going to be completely black, and so is the ground, except for the area right under the ground there will be a tile so you can see where you can go. I want to add all the situations that will trigger specific animations in the characters, like swinging on vines, crossing a horizontal vine, bouncing on springs, using poles, getting hurt and swimming. Have I left any out?

Anyway, how can I use water in a tileset that doesn't have it? Can you use water anywhere? How? I know it must be possible because I saw a Diamondus battle level with water when I played online before. But I deleted it from my cache folder already.

Is it easy to make water? I'm really new to this.
