This was awesoooome!
Great game, felt really polished. The cute little animation on the character when jumping was superb.
All of the levels were interesting and fun to play through, maybe felt a bit too slow though.
While I did like the mechanics a lot, they were great for platforming/puzzles, I would like a bit more freedom and difficulty. For example, moving in "big fish" form was a bit too controllable in my opinion and could have been more fun (for me). But the mechanics were still great and fit the theme perfectly.
One thing I didn't like at all was the camera moving with the mouse cursor. It was like super aggressive and a bit disorienting.
But man, I could see this polished into a full game with more levels.
