Hello! I played on Vive headset with Index Controllers on a 1070 GPU.
I see you matched the theme by stating that trash (above) ends up in oceans (below). Neat little interpretation.
When playing, I noticed you submitted a non-shipping build (it tells me lighting needs to be rebuilt). I also noticed that I had terrible frame rates - steam graph was in the 40ms and it wanted to be around the 11ms mark. This made playing the game hard and a little nauseating.
However, the concept is cool and the environment was pretty! I think if added a tutorial, a better 'end game' option (e.g, more than just pick up 20 pieces of trash), and fixed the performance, that this could be a fun little VR game to explore the ocean in!
Overall, good job making a VR game in such a short amount of time - it's not easy!
