This game was super cute! I loved the cel-shaded look, and swimming around as a little fish was really fun. The music was also super pleasant and atmospheric. The controls were a bit awkward at first, but they really did a good job of capturing the feel of swimming around as a fish.
I'd love to see this get developed into a full game, with more characters and a story! Although when you do, I hope the little fish gets more capabilities... a dash function would be nice, or perhaps a sound to make that would call Idra to you. I like the gameplay mechanic of using Idra's light to guide you through darkened spaces!
(To be honest, I was a little worried that as an anglerfish, Idra would try to eat me! ;3;)
