I swear I thought I heard that doorbell jingle in here lol. For what you were aiming for, you've hit it perfectly. It gives that calm respite feeling that you get after a tough battle, and you finally get a save point. I've never heard something like this, and it's really really interesting, I'd like to see more of this! I really like that main instrument, the sort of string/piano/pluck sound (forgive my terrible ears lol)! Only things I would say is that parts of the song feel off time with others, and that it seems a bit long.
For example, at 1:06, it seems a bit off. This seems to happen a lot in the song. Nothing major, just something that got my attention. I'm not really sure if this is something you would want to fix, however, because it could very easily be the thing you want.
The song is also a bit long. It's an ambient song, so there's nothing super duper catchy in it. But I did feel as if it started getting really repetitive, around 1:50. I started to do other things while listening, which might be what you wanted, but it does feel stretched. Maybe you could make this shorter, and into a loop?
But take my words with a grain of salt, I've never listened to Ambient, so I could be completely misunderstanding things. Main point that I want to get across though, you're doing great! I'd like to see more from you! Good luck!
