I'd say you succeeded in the executing the water shader; it felt like I was underwater. The graphics and sound design are the stand out elements here. The enemy designs were varied and interesting - the unassuming pufferfish kept sticking me with their spines, and I found myself completely avoiding the bully sharks, or letting them eat each other and grabbing the drops lol. The controls took some getting used to at first; it reminded me of RE1 for PS1 where left and right rotated you and up was forward movement, but the clunky movement made sense as a sea turtle in an underwater world. The splash screen was gorgeous, despite the glaring misspelling ;) Great execution overall!
