I haven't checked for bugs yet but the procedure to activate "easy mode" is the one I wrote above. (Basically if Axy gets slightly injured when closing the statue's mouth it will be more difficult to get out of Ajoora's butt because he will have an allergic reaction, but if you insert the piece of iron into the statue it will be enough so that Axy will not suffer any injury and the allergy won't swell Axy that much)
As for the story and the characterization of the characters, I'm working hard on it because I think it's a fundamental factor in every good RPG, but I might have some bad news...
The combat system uses many keys on the keyboard, for example "q" to jump. "w" for slide, "a" for attacking with tools, "s" for attacking with magic, and many more for quality of life. With the spacebar you use the normal attack but I hope you can use the others too otherwise it might be boring to only use the normal attack to defeat enemies. In practice Burning Soul is an Action RPG, although there will be "special sections" with Axy where the fights will be turn-based like classic RPG 😉
