I really enjoyed this game! Visually it's stunning and I love the color palette used in each level/scene, there's a lot of artistic and modeling work in this game.
On the second level, if you release the fish while you are in the water tunnels, you will be launched out of the tunnels and fall into the void. It has other bugs, such as getting stuck in some areas and being unable to move, tut these are things that can be fixed later, and the game itself is very enjoyable.
