Gameplay : 5/5 - Very clever. Reminds me of a game on my CPC464(!) which was playing on treble and bass. I was looking forward an opportunity for making it again, for a gamejam. You did it first! :)
Visuals : 4/5 - Nice but a bit sad and monotonous
Audio : 4/5 - Effective but simple. Ticks are a bit slow I think, even very near. The phone ring, playing on volume isntead of interval, was a very good idea to renew the game after 3 objects.
Enjoy : 4/5 - Interesting to play. I lacked a bit of fun however
Theme : 3/5 - I did not really get the link between "isolated" and searching for my phone :)
