Lol, pretty similar concept, yes. i put more effort on tech implementation (the way waves renders andd reflect) rather than gameplay,/ so gameplay is not as good as i would want. Initially I wanted to make more horror style game inside real house location.
i found a game even more similar to my initial idea
