Hey there DepressedHarold. I'm in the process of playing your RPG. You've gotten a hold of RPG maker and some high-quality sprites and effects, and I can see you have a lot of work in this. I'll be adding here as I get it, but since this is an RPG, I don't know if it'll take me 2 hours or 200 hours to play through the whole thing. So be patient with me, as I'll be updating and messaging with things I find along the way and suggestions! And... since it's an RPG, expect this list to get extensive.
1) Door and paths! You have numerous doors that appear to be open but I can't walk in them, in particular the first town (not the castle). Also, there are paved paths to the side of buildings that hint at being able to walk behind or go in side entrances that don't do anything. To be fair though, these make the paths looks dynamic, but now I will forever have to check every single one to see if I'm missing something important.
2) If you have an NPC standing behind a desk, I think it needs some basic dialogue, something there to let me know to come back later, or that NPC doesn't do anything like a "..." or something. In particular 2 of the 3 people at desk in the building to the left of the bar in the castle don't talk to me or do anything. The center figure does *thumbs up*
3) There are lot of sprites I can climb on top of, like bookshelves and things like that, again, I keep thinking these are secret paths, but really they are sprites with no boundaries on. The shop next to the hotel in the 2nd town.
4) There are a lot of typos. Also the dialogue of characters seems to be inconsistent. Sometimes you skate in and out of full words and then use shorthand and abbreviations. It's hard to get a sense of the characters when they keep changing how they talk.
5) 4) I love the random NPC with weird things. "I like tramping, does that make me a tramp?" OR "I'm looking for a job.. / I'm walking in circles..."
6) When buying items from stores, you have 2 stat screens, the first (top) is the actual item, the 2nd (right) is my currently selected character. Maybe just add a red color or something to items my currently selected character can't equip. I keep buying items thinking I can use them when I can't. This is mostly me, and not a design flaw, you've got it there. Just asking to make this slightly more obvious.
7) When i enter town at some point I force interact with "cute girl" and get the catmonster prompt. However, going inside the inn, I can interact with that same NPC upstairs like we've never spoken before. This carries on 2 separate dialogue with this character. She probably doesn't need to be inside the inn, after I've talked to her outside, or she's in the inn at first, and just has a hint at her future quest. Also, the game locks using spark fighting the cat monsters. And going back to the inn and resting spawns 2 of her, one that joins my party, and 1 that stays there with the dialogue. The one from outside disappears, so that must be the one that's correctly configured.
8) Autopathing doesn't take me around ladders or stairs, these should be considered obstacles when using mouse controls, especially in caves.
*Update* So it's a shorter version with the single main questline for now. You're off to a great start.
And there is still a lot here to expand on like creatures and expanding on a lot of the interaction from the first cut scene, reentering the tournament, etc... etc... . I hope you get more soon!
