It's rare that I download games outside of horror and I found this one to be a cute little arcade game. I have a few suggestions though. There should be some explanation on what the colors mean, the floating text, if your connection with another grows as you walk or if it's the time spent together, stuff like that. Also, the lack of music and sounds makes the environment a bit bland. I imagine a few "bubble" type sounds should be played once the player interacts with another body and maybe a soft piano or strings as the BGM, not too complex. Lastly, I don't think downloading a game build is necessary. You should try turning it into a flash game (web play). Nice work though. Cheers!~
