Cool ambient soundtrack, but sometimes gets a bit repetitive. For example Dem Ende entgegen has hardly any change, only new instruments added. You should probably change the chords and melodies a bit from time to time, because if they are repeated too many times they can get a bit jarring to listen. You also don't have to only add instruments, sometimes removing some in the middle of a track does the trick and makes the music more interesting to listen to. Removing some instruments can give some more breath to the listeners ear and can give more space for different instruments. I like Die Einkaufshalle with these drums, a bit different than the rest of the soundtrack, but I feel that it's a bit too short and would again get a bit repetitive if played in loop inside a game. I think that Ein Kindeslied is structured a bit better, becuase the melody and chords actually change throughout the track, but this time the track even lacks a bit of repetitiveness and sometimes the melody sounds all over the place because of that. You need to find a sweet spot between lack of repetitiveness and too much repetitiveness, because if the track doesn't have any repetitions then it won't be really memorable, but if it has too much then it can get a bit annoying to listen to. Now Einkaufshalle Start has more of what I was talking about, it's repetitive, but not too repetitive, has some instruments added, some removed, I liked that one. It's really hard to judge Hochfahren, because it's more of an ambient track, a bit of context (where it's meant to play in the game) would help. I like Unbekanntes Zuhause, the melody is a bit more memorable than in other tracks and uses cool sounds, idk if there's anything else I should say about this track. Wahrheit is a really cool, calm track too I really like the reversed guitar.
Also the SoundCloud link doesn't work, so I think you should fix that
