Suggests enhancing the main character's design with more unique outlines, specifically mentioning a witch's peaked hat or a small touch like Anya in Spy x Family, to improve visual distinctiveness.
Your theme is really good imho: It's got those "smarty-fruitie-tootie" gummy-drop, sugar-bomb sweetie vibes ! The main character having a more unique outline would be a nice touch - possibly a little Witch's peaked-hat bobbling along her head somehow slanted to one side or even just a small touch as per Anya in Spy x Family? Mario has it all: * Physics of movement * Character design * Environment and obstacles including fun goons I think Celeste is note-worthy because it takes basic physics of gravity up-down then adds core air-dash and wall-bounce so you now have left-right and diagonal to the mix. Grappling-hooks, magnetic boots etc are all other contraptions for adding different dynamics to the physics of gravity.
