Hmm, a retelling of Marisa starting to become a magician?
As a respectable beginner magician she can fly with her broom. But why does the broom only activate when Marisa's falling? Not that it matters much, just like her jump. Just that it feels a bit odd it doesn't activate the moment the key is pressed but rather "later".
In this game jumping precision is important due to the various bullets flying that sometimes require tight dodges and the emphasis on platforming. I think being able to control the jump height would have been great.
These aside, this game as a survival platformer is appealing enough. Maybe even more so for speedrunners.
