Interesting game, very self-explanatory. I liked the oxygen meter that I had to pay attention to every now and then. There was a nice balance of mystery with the beacons and and everything, and I liked the surprise after linking them all. The game seemed to restart with more beacons and wanting me to replay, but I felt satisfied enough and ended it there. Although the beacon mechanic was fun, it felt like it needed something else dynamic, since it was relatively easy to use both visual and audio queues to get them in focus.
