I think, the fact that I went to watch "Hilda" after playing, alone tells how good this game is.
Considering that Gelda was made in less than two weeks, it's quite impressive how much visual content it has. I really hope to see more. I'm also glad to see fixes and adjustments in gameplay throughout the Jam.
One addition, I think, is necessary after the game will have more levels - option to replay them to get sketchbook pages missed on the first playthrough.
