This ocean is wonderful *_*. In case if you have some kind of desire I would be very glad to see a dev-post about the creation process.
Gameplay is pretty basic like in the original game (which is good). The mood is represented perfectly. Sad that the game doesn't have a sound, but in total, the entry leaves positive feelings. I liked it!
PS. I also used dsoft20's shaders for Unity3D to represent a PSX style in my entry. I was glad to meet someone else who works in this direction.
Good luck with future development and voting!
