Your art is very colorful, I like it! The character felt way too floaty for my preference. The drawing mechanic was fun. You were quite ambitious with the story for a game jam game. My advice is to maybe keep it a bit more concise. A lot of people will bounce off your game when they are immediately faced with a wall of text, which is a shame because then they don’t get to play your game.
I also liked that you had an area in which you could not draw. I think that is a smart idea, but I would suggest making it a bit more visually clear or having your character comment that they can't draw there. Pressing the G button in the game felt very unnecessary. Just make the player continue to the next screen when they have collected the key and touched the gate. It also took me a bit to realize that the music was muted in your game options.
Good job on your game!
