This one is great. Weirdly it reminded me of Happy Wheels with the physics-based platforming (v complimentary). The last level is evil, but I just about managed to get it on my very last try.
I genuinely really dig the 3d-effect on the waves coupled with the smooth tunes in the background. Gives it almost a hypnotic quality. Those two components are pretty contrasting to the rest of the aesthetic (the fish-returning to the ocean theme), but to be honest, I think I prefer the hypnotic element of this game to the cute fishy element. That's 100% just a subjective opinion though.
Great job dev, loved it.
