Interesting puzzle concept, but I found you could pass some levels without the fish.

This was kind of weird game to me but I like it. I still don't know how it work even though I passed 4 - 5 levels :)). One minus thing is that the fishy is easily stuck if it touches the wall. It makes me feel a little mad when I am not able to control the fish.

This was fun and I like the concept of one character dying and teleporting to the other, but it was pretty annoying when you picked up the 1 to move it and the fish went there and killed himself. But when that doesn't happen, It's a very nice game.
