Oh man, this sounds really happy! You really captured that Nintendo feel! I loved the sweepy dream-like pads in Stage 1, but it did feel like it struck a slightly different tone than the rest of the soundtrack. When it opened, I almost got a Boards of Canada vibe from it for a second. I could imagine that could fit a dream sequence though. Would really depend on what the game was trying to do at that point.
And haha, that fanfare is great!
Man, you really nailed the mood on this one. Really well done!
