I love the writing, it's silly but i think that is exactly what i like about it. The Ori-like "here you go now you can [double jump|jump super high|dash through walls]" is not that unique but executed pretty nice here i think. The music...we don't have to talk about that. Creating music for a game jam is awesome and this is no exception!
The flaws are maybe the controls, visual variety and physics (as already mentioned in other comments). I think it was not possible to jump when you were already running in any direction. And the jump had a small delay between pressing and actually jumping, which does not feel great in my opinion.
Other than that, i played it to the end and enjoyed it! Nice Job!
