First off, I've got to say that's the dopest preloader I've seen in forever.
On to the game itself, though, I dig it! The song fit the atmosphere, and the artwork was great. I felt like a lot of care went into that intro cutscene especially.
Once I was on the water, I clicked with the gameplay pretty quickly. A little part of me wishes there was more to do (i.e. collectibles or upgrades), but I think the real beauty here is in the simplicity. Plus, the waves are spaced apart just far enough that I never felt like there was a lack of engagement. The gameplay is tricky enough that I don't think anyone will survive too long and get bored, anyway.
I do wish there was a full screen button, though. I'm playing on Chrome, and a decent chunk of the top, bottom, and right-hand side of the screen were eaten up by the browser.
All in all, fun little game with cute art!
