Amazing puzzle game. The level design is awesome and the puzzle mechanics are really challenging. Loved the way how you eased in the player with simple levels to understand the mechanics and then gave a harder level with those mechanics. 
Great job!

The puzzle design is really well thought out, especially for a simple mechanic. Just a solid game all around

This a solid entry ! It's tricky, but in a good and satisfying way ! Great job !

I liked the fact that the level is way bigger than the puzzle itself, added a lot to the mood.

Nice! The added level of popping oxygen to gain your 'moves' back was a nice little twist on a classic. Also, loved the look!

I love the art the game has a really good look all around to be honest. I also like that you have a bunch of moving or animated things in the levels adding some motion and stuff. The music is also great, very chill and fitting for the game. I also really liked how you do the puzzles, especially when you add the other fish managing the movement of multiple fish at the same time is fun puzzle wise. Anyway, you guys did great this is an awesome game.
