Feedback on Game Idea Thread

Hey guys, I want to make a 2d action platformer that has some RPG elements. What I have for aspects of the game so far:

• 6 characters, each with their own stories (broken into chapters) and distinct classes
• Level progression/skill tree
• Randomly generated levels (take a chapter and the bosses in that chapter, shuffle them, and have unique levels and order for each playthrough)
• Upgradable weapons, armor, and equipment
• Pixel art
• Class-specific powers and weapons
• Difficulty selection
• Score system (can use score to make purchases, nab upgrades, and acquire skills)
• Power ups (wear off after certain amount of time)

My inspiration was a cross between Risk of Rain and Kingdom Hearts, with the action of Risk of Rain and the emotionally driven stories of the characters in the Kingdom Hearts series.

Sorry if this is in an improper format or if this is in the wrong section, I'm new to this. Also, I'm open to suggestions and appreciate any feedback! Thanks!
