Thanks for the feedback, friend!
I'm glad you liked the movement mechanics and the underwater theme. These aspects were some of the main focal points of my project, so I'm really glad people are finding them enjoyable.
Many have commented already about the performance issues, so dealing with this is first on my priorities list after the voting is over. Thank you for highlighting it once more, and sorry for the inconveniences that might have spoiled your experience.
And I will absolutely try out your game, you don't even need to ask :)
