Really didnt like the mechanics and logic of the game.

it controls its self

The sudden difficulty change between levels 5 and 6 was... quite surprising.
There's no "replay" button, in case you accidentally fall in the flaw (which actually happened to me), and there's no level selection, nowhere.
Nothing new or interesting to play.

it bored me but thats because of a fatal concept flaw(for me anyway) the only way its hard is if you go for the fish instead of trying to pass the level and that kind of thinking leads to bad puzzle games not bad as in poorly made bad more as in not fun enough to play without something that sets it apart bad

The game is great, but the recurring music can get annoying after awhile, It would be a good idea to change the music up a little bit and maybe put a counter of how many fish you have and how many are on the level so a person doesn't try to find fish that don't exist or miss any if they want a perfect score...
