This game presents an answer to the age old question of "do you ever feel like a plastic bag?"
In which the answer is "yes. Yes I do. Now I'm off to kill some sharks." The game has an inherent dark humor to it, seeing as you go around killing poor sea animals with plastic in a way not dissimilar to real life, but the mechanics of it are fun. I think adding some sort of plantlife or other decoration to the ocean would give it a bit more to the ambience, as I agree with another commenter about things feeling a bit empty, but I still enjoyed the game regardless. 

The ocean felt a little empty for me. Otherwise it was a fun expierience.

I liked the concept, loved the simple art too and the music fited the game a lot. Nice job.

Got into character as a plastic bag and killed a sea creature,  10/10.

In all seriousness it's a fun little game and I enjoy the dark, tongue-in-cheek humour of the whole thing.  I played for a while because I wanted to kill a shark, and I was not disappointed. 

One small issue I had was damaging items seeming to be deployed and not doing damage,  and I'm not sure if it was a bug,  or if I was just missing my attacks and there wasn't any kind of feedback for that.
It didn't ruin my overall experience though,  I had fun with the game.
