I'm working on a plaformer game and for one of the levels I'd like it to look like you underwater. The look I'm going for is that slightly distorted/wavy look with light shining down from the top. I hope the GIF I attach works because It's exactly what I'm looking for. Volnaiskra's Spryke game has this effect in it, from what I've seen. That game looks absolutely amazing by the way.
