Since the comments on the challenge entries are disabled and I'd love to get some more feedback to our game, I am now posting the game here in addition to our challengepost page.
The Captain took your Ducky is a puzzle game in a hexagonal water world. I made this together with Floran Rappel. It was our first VR and also our first 3D game, so it was pretty tough for us, especially as we really wanted to make everything by ourselves. Also as it now turned out, many of the performance issues we were fighting might be caused by Android Lollipop. But in the end, we made it in time (though we had to skip many of our ideas) and our version runs fluent on Lollipop and should run even better on KitKat I guess (would love to get some feedback on this).
We couldn't make some great screenshots in time, so I added some better quality screenshots on a separate page.
