The song has a retro PS1 style to it. It brings across dark and unsettling vibes, which is very adequate for a scenario in which the protagonist is on edge and cautious. I think the ambient route is a good choice especially for a game setting since it's something that doesn’t' have a clearly defined end point and would make it easier to loop. Musically, I appreciate that even in an ambient style, it's not a dormant song. Compositionally it's rather busy, which helps put forward the unsettling and creepy vibes this is trying to go for. The choices of synths and percussion samples feel raw and simple, which I think bring across a retro style. However, the mix could benefit from some EQ work since the high frequencies are a bit piercing. It also doesn't help that you have long cutoff style synths happening (or it might be heavy reverb sounds). With the long cutoff synth playing a lot of notes quickly, the pitches collide and make the mix sound busy. It is a good choice if you don't want the notes to have a clear beginning and end, which add to the unsettling nature of the song, but with the state this mix is in currently it comes across as an effect that isn't clean. It won't feel as refined. That's really the only critique I have though. I see that you have some gameplay video linked in the description, and the song works very well with the game/visuals you've got. I'd say this is a pretty good work. It's a little weird, but for not hearing you before I think this shows some decent talent.
