You've got some pretty cool work, Lavender!
I was taking a peek at it and it seems like you're quite experienced, like DioShiba said. Very nice waterfall (I know how hard you worked on it, I feel you, the struggle is real T-T), trees, and rockface; They all look like they belong in a game already!
I use Gamemaker personally, but I've heard that Godot is easier. Guess it just depends on how quickly you want to pick it up, or if one engine is doing more harm than good. I use Gamemaker's sprite editor for smaller sprites, but I do the rest of my pixel art in Pixel Studio.
I should probably consider doing progress shots more...
