How well suited do you think this retro style is to the current indie scene?

Depending on the context in which it's supposed to be used it could be suitable or not :P A useless remark, maybe, but it's hard to say anything about suitability without knowing what the track is supposed to accompany.
Apart from that, it's a nice track. By not adhering to any obvious tonal centre most of the time it becomes ethereal and mysterious, and when it does finally stabilise at 1:49 it feels like the dramatic story is about to unfold. The sound design is nicely done too; it comes across as retro because of the pure waves you use as a single instrument but modern because of the way you use them and the delay you've added.

I'm aiming to make a 2d-sidescroller type game with a low-fi fantasy feel to it.
Thx for the breakdown :)

Sounds great and retro!

Can you tell how did you create the sounds? Is the SNES soundset a thing you can get from somewhere like a VST-instrument or a real SNES soundchip?

About suitability, it really depends on the game. The song sounds like background music of a storytelling scene or a slowish adventure scene. Do you have any reference-game for the sound design & music and the actual gameplay?
