This game is insanely fun, I have barely done any combos (1st run without Size, 2nd was a failed Key-Flip that turned into a Key-Flip-Flower where I didn't use Flower but couldn't manage not to pick it up, and 3rd was a Fire-Flower) but I still got my mind blown a lot. Also got the lever in trophy room but I don't have access to the left side yet so I'll have to figure out more.
On another note, idk why but the windows build isn't working for me, so I have to play on Web, which is fine but I feel like I should mention it.
