Dusto! Great to play your game!
It's a cute little story, and I love the concept. Your little character model is amazing, and I love all the animation. I do think it could use some complication. At the moment, it seems like there are two states: hopping and at rest. Maybe the addition of an "ability" or two, like a sprint or springy long jump, could add to the intrigue. Also, the flowers and fireflies are very pretty, but a little change in scenery might be nice; the top down view isn't bad, but it doesn't really let us see our surroundings that well, which means finding anything can be difficult, especially with how dark it is.
I think this is the start to something really nice. You have a lot going for you already, and I think with some work this has legs, as they say.
