I have a lot of hope for this game. As soon as I visited this page I got hyped and bought it. As most reviewers are saying, I wasn't able to play it at all really due to the poor optimization, which I am aware you are fixing. Additionally, I feel that there could be more options to better benefit the player in the settings. Furthermore, it might just be me, but I'm having trouble looking around my environment while swimming.
All in all, I feel in a month or so time I will definitely have a lot of hours on this game. I really enjoy the idea and its potential.
