Hi Pschnorbus, I went ahead and downloaded it again to try it out with the controls. Sorry I missed those on your project page before. With the controls, I was able to get much further to the third island. The story seems quite poetic, and I appreciate that the game is both a reflection on the past (Rewind) and a focus on the kite/"Wind" theme.
I have a few other critiques now that I've played more of the game, and you haven't had much feedback yet so: The player in "kite" form looks a little plain. Once I knew about the kite aspect of the story, it made more sense, but initially I thought it was a buggy model. Maybe add a texture there? The boat mechanics actually felt pretty good with the wind behind me, but going from the second to third island was rough because the wind wasn't pushing me forward. Took quite a while to get there. Maybe the wind can change direction toward the next objective? Overall, I enjoyed your submission!
