I haven't played the game, but I noticed it looks like you're using RPG maker assets, but the game is made in Game Maker. You should know that using RTP RPG Maker assets in any engine outside of RPG Maker is against their rules, so I'd suggest switching them out.
(I hope I'm not coming of as antagonistic, I just thought it would be good to know. I doubt Kadokawa, or whoever owns the licence, will notice but still. Better err on the safe side.)
