It needs something else to be playable… it could have possibilities if you add other mechanics to what you already have.

Unclear instructions, I don't get the goal of the game :/

Also, as the fish is moving I think that if there's no animation for that, at least when you move to the right, the fish should turn its body to the right.

The mechanic of the separate fish and the light bulb is interesting, but could be executed better.

Without a goal, this game doesn't seem that much fun, but the premise is original and with some more effort, this could be a really nice game.

For now, however, I don't find it that enjoyable, sad thing for such an original concept.

I hope for next jam you get to have more time to dedicate at your game so you can develop a better one. It seems like you are very creative, but probably busy or kinda lazy (I don't guilt you, I'm lazy too lol) just that you should try to dedicate more time for your game, because an original concept is very important, but the execution is more.
