Very charming game. Graphics are simple and yet they fit the game well. Music is top notch, liked how there was different music for different settings/screens.
I think you just about managed to meet the theme requirement with your Scaley Scaled down fellow Scaling a mountain too xD
For improvements, I'd say work on the Jump to make it feel more responsive. Felt like sometimes I would fall off the edge of a platform instead of jumping while running forwards. Some nice little SFX here and there would be good too.
Overall, nice submission. Good job!
