I've gotten to track 3 and already we've played a game within a game, now there's a waiting game too?
And now there's a chasing game? HOW MANY GAMES ARE THERE??? just kidding, nice job on your soundtrack! A fun little story and game concept. A couple of notes:
First off, I definitely recommend putting your tracks in a playlist to make them easier to listen and rate and you could make sure they are placed in the correct order. (You can do this yourself by going to your tracks page and clicking the three dots on the right of the track, but if you upload them all at once SoundCloud can do this automatically by making them into an album)
Compositionally speaking, the soundtrack has a huge range to it and conveys pretty well with the setting you've described. The composition is varied and each track feels pretty unique compared to the last, without ever straying to far from each other as an album. My only critique here would be that a couple of the tracks go on a bit long without having too much change or movement.
Sound wise, the piano is lovely in "Romantic," but it could use some more dynamics/velocity changes, especially in the latter part where the deeper notes come in. In "A Game on The Phone," there is a cymbal sound that is only barely audible, to the point where I'm not even sure if it's in the whole song or just some of it. "Chase" has a lot of harsh low-end in the left and right that could be EQed out, and most of the song has an instrument that's making a clipping sound, possibly from the way the notes are being played (depending on your vst, synth, etc; but probably just too close together, as they aren't having enough time between notes to play out the full length of ADSR on that instrument)
Overall though, this was a really unique and fun little OST that had some cool and interesting ideas. Nice work!
