Good work! i got upto 900+ then just quit.

I like the concept, and audio used.

i was confused as to what i was doing as there was no explanation of sorts.

it would be great if there was a goal to the game, as once i knew what was happening, it was like... okay.. why am i playing?

as the health to collect, was appearing at a constant, and fish where coming to me, i can just aim for that, and get it, theres no real way to win or lose in game.

It would be great if you added (as per ur comment above in "use of the limitation") which is for you to illuminate the deep sea, that you added some exploration, going through caves, other variety of fish, maybe ones that are bigger then you that could kill you.

Lots of fun!

Nice game! The gameplay is simple and the objective is clear. Though there is little difficulty and sense of progress (you can go on forever). The music is fitting and graphics are the best.

Simple and neat!

I really love the atmosphere. The lighting makes it feel spooky, but the music lightens it up just a little bit and the effect is really nice. Great job.
