Took me a while but I finally beat level 6! I'd also like to think I beat the secret area too:
Fun little platformer that was actually fairly challenging at times and made me want to explore to see if I could find more hidden areas (I managed to climb on top of the Cave/Desert part of the middle of level 6 and *almost* tried some leaps of faith with the cloud to try to find other areas, but I didn't want to prematurely end my (finally!) good level 6 run.
Nice entry, especially if it's your first with godot.
